Plane Mirror Reflection
The most familiar mirror of all reflecting surfaces is the plane mirror. Visible light radiation is reflected through its making, which normally is consisted of a planar or flat piece of glass, on which a silver coating is placed which produces a reflection of the visible light radiation. The motion of this radiation, is inevitably, quite unique. Its motion is like a wave in nature, but it can be broken down by drawing rays that demonstrates the direction of the wave propagation. The use of the waves, allow individuals to decipher the common features of reflection, which includes a basic relation between angle of incidence and angle of reflection for the radiation that is in reflection from a surface. The meaning behind angle of incidence and angle of reflection deals with the angle between the respective ray, being incident or reflected, and a vector that is considered normal to the surface of the mirror. For a plane mirror, the vector that is normal is considered perpendicular to the plane of the mirror. There is a concept that relates to this that is called, “The law of Reflection,” which states that the incidence angle for an incident ray is equal to the reflective angle. Here is an illustration of this law:
Reflection of a Plane Mirror
The consequences that are associated with the law of reflection are quite intriguing. For instance, if you place an object (any object) in front of a mirror, the image appears to be at the same distance behind the mirror as it is in front of the mirror. Nonetheless, its appearance configures that it will appear to be situated at the same distance behind the mirror as the front. However, the image will actually be horizontally inverted (meaning the left of the imag...

...gle with our naked eye). This error can occur in a lab when he observer’s eye is not squarely aligned with the instrument at hand being used. We may have read too high or too low of a value when using the protractor to determine an angle and our data may have been altered by a very small degree of numbers.
Lastly, personal errors may have affected our data points from small, yet costly things such as carelessness, poor technique, or even one of my group members being biased or myself. Being biased during this lab could have taken place because of a prejudgment we had towards how we hypothesized the data should have resulted in. Forcing data to equal to expected measurements in our angle may have caused a small alterations in our angle degrees. Personal human error always plays roles in skewing data during labs, and took place during the course of our lab as well.
There were no significant error factors that may have affected the arrangement of the lab experiment. Everything went smoothly with relative ease.
...ossessed with three dimensional attributes. The optical effect may be explained by the fact that the human eyes see an object from two viewpoints separated laterally by about six centimeters. The two views show slightly different spatial relationships between near and near distant objects and the visual process fuses these stereoscopic views to a single three dimensional impression. The same parallax view of an object may be experienced upon reflection of an object seen from a concave mirror." (http://www.freepatentsonline.com/4229761.html).
In this experiment, there were several objectives. First, this lab was designed to determine the difference, if any, between the densities of Coke and Diet Coke. It was designed to evaluate the accuracy and precision of several lab equipment measurements. This lab was also designed to be an introduction to the LabQuest Data and the Logger Pro data analysis database. Random, systematic, and gross errors are errors made during experiments that can have significant effects to the results. Random errors do not really have a specific cause, but still causes a few of the measurements to either be a little high or a little low. Systematic errors occur when there are limitations or mistakes on lab equipment or lab procedures. These kinds of errors cause measurements to be either be always high or always low. The last kind of error is gross errors. Gross errors occur when machines or equipment fail completely. However, gross errors usually occur due to a personal mistake. For this experiment, the number of significant figures is very important and depends on the equipment being used. When using the volumetric pipette and burette, the measurements are rounded to the hundredth place while in a graduated cylinder, it is rounded to the tenth place.
Possible sources of error in this experiment include the inaccuracy of measurements, as correct measurements are vital for the experiment.
Discussion: The percent of errors is 59.62%. Several errors could have happened during the experiment. Weak techniques may occur.
My views about Ehrenreich’s novel that it was filled with educational details of minimum wage job occurrences. The author captures concrete memories of her experiences of several job positions. Working in several jobs of hard manual labor is exhausting for the mind and body. The job experiments involving all these jobs to see what many struggling people endure on a daily basis. I thought the experiments resulted in average, and intolerable work environments. Working one or two jobs was needed to survive and pay for necessities. From my perspective, it was a useful trial to show readers the hardships people of every culture deal with constantly.
One possible source of experimental error could be not having a solid measurement of magnesium hydroxide nor citric acid. This is because we were told to measure out between 5.6g-5.8g for magnesium hydroxide and 14g-21g for citric acid. If accuracy measures how closely a measured value is to the accepted value and or true value, then accuracy may not have been an aspect that was achieved in this lab. Therefore, not having a solid precise measurement and accurate measurement was another source of experimental error.
The term Wesleyan Quadrilateral is a theological method used to study scripture. It was believed that theologian John Wesley studied scriptures in the Bible using three lenses, hence where the Wesleyan Quadrilateral gets its name. These three lenses are tradition, reason, and experience. While quad means four and tradition, reason, and experience are only three terms, they each communicate a way that scripture can be studied, therefore the term scripture completes the quadrilateral. It is important to study scripture using the Wesleyan Quadrilateral because Wesley was known as being a relevant theologian and his views on scripture have lasted over two centuries. The Wesleyan quadrilateral is still relevant today as it provides a method for discovering the things of God, ourselves, and lets us know who God really is. For the purposes of this reflection paper I would like to summarize the four components of the Wesleyan Quadrilateral and then reflect personally upon each term as how it relates to the Christian theologian.
This reflective essay will lay emphasis on one of the learning needs I have developed during my two week taster placement in hospital. Reflection helps an individual build upon their skills and makes room for self-criticism as he or she can contemplate upon actions and make relevant changes (Taylor, 2000). I will be applying the “What”, “So what” and “Now what” model of reflection by Driscoll (2000) in this piece of work because it is a more coherent and comprehensible approach to follow when writing a reflective account and is also an easier guide to writing reflections. The learning need I chose to reflect on from my learning plan is having a better understanding of diabetes and the 6 basic medications used in treating the condition since it is a common illness on the ward I am have been allocated on for my first placement. The timescale set for achieving this objective was by the end of my two week placement that is from 27th January to 9th February and I achieved it with the help of a host of factors. In this assignment, all the names of the patients and wards have been omitted and indicated with letters and numbers for confidentiality reasons as stated in the Nursing and Midwifery Council (NMC) code of conduct (2008). The paper will primarily touch on the type 2 diabetes and furthermore on the achievement on my learning need.
Mirrors are first introduced in part one of the novel where Clarisse is describes as a mirror by Montag. Also presented by Granger towards the end of the novel, the mirror is a symbol of the lacking self-reflection but also it cure. Mirrors reflect a perfect image of a person back at them – an image that is neither tarnished nor beautified. Mirror here are a symbol of seeing within one’s soul in pursuit of rebirth, and are a tool to be used in the search what has gone terribly wrong in such an empty society. In a society that lives without living, thinking or feeling like Montag’s looking into a mirror ma spark a thought, and a thought may spark that internal rebellion. Furthermore, metaphorical mirrors are of equal significance when understanding this symbol. Clarisse is Montag’s inner mirror; she reflects the personality and life of Montag back at him, allowing him to learn and question what he sees. Montag is also Faber’s mirror – he reflects Faber’s recent emptiness and his cowardice at not attempting release society from its suffering. Mirrors are a great symbol of self-actualization that leads to rebirth in the novel Fahrenheit
In the book, “The Element” by Ken Robinson he discusses how different education systems all over the world are but focuses on the education system in the United States. The reason being is that he believes that there are faults that need to be fixed because it doesn’t focus on the students individually and discovering their “element” but, on academics, business and state testing. Robinson claims that education itself is supposed to be a process in which it develops all resources.
The Double Helix tells a tale of fierce competition, perseverance, and scientific innovation as we follow James Watson and his cohort Francis Crick on their quest to discover the secret to life, the structure of deoxyribonucleic acid. Although already fascinated with DNA, Watson struggled with finding chemistry exciting enough to learn it in depth. He had studied birds in college and thereby managed to avoid any formal chemistry or physics courses. As he later pursued a PhD in biochemistry, he realized he could put it off no longer and attempted to learn organic chemistry at Indiana University. However, after a mishap in the lab, he was encouraged instead to study nucleic acid chemistry with Herman Kalckar in Copenhagen. There, his mind strayed from his work and he began doing unauthorized research in the lab of Ole Maaløe, studying phages. Herman stopped teaching Watson after going through a divorce with his wife, and sent Watson off to a scientific conference in Naples. Although he was bored by many of the lectures, Maurice Wilkins’s talk about X-ray diffraction fascinated Watson. He was struck by an X-ray diffraction picture of DNA that Maurice presented and was determined to study the acid. He later got to know more about Maurice’s colleague, Rosalind Franklin, who was proud, stubborn, and very difficult to work with. Watson greatly admired the lecture given by the renowned Linus Pauling, who had discovered the structure of the alpha-helix and was thought of as the leader in DNA research in the scientific world.
ways as I have explained in this essay. It is a fact that The Mirror
This lesson is designed to review and reinforce a few important concepts about plants (e.g. Needs, parts, sequence of planting) and to also guide the students through applying a few scientific inquiry (e.g. Making observations, experimentation, discussion, reflection, reporting results etc.). The students have previously planted corn and bean seeds and today’s lesson has provided the students a chance to see the results of the planted corn and bean seeds. Additionally, seeds have been planted under and growing under the following conditions: without water, and without soil. The students see the results of these seeds planted under these conditions for the past week. Two plants in particular have already been grown their growth has been
There is also the potential of human error within this experiment for example finding the meniscus is important to get an accurate amount using the graduated pipettes and burettes. There is a possibility that at one point in the experiment a chemical was measured inaccurately affecting the results. To resolve this, the experiment should have been repeated three times.
