Photonics / Optics Specialist Often overlooked, light plays a big factor in everyday life; it is the key to survival. Light is used for everything from cellular respiration to the lasers in DVD players. Photonics and optics both involve the study of light. Photonics is the study of how light can be used to transfer information. Meanwhile, optics focuses mainly on the way light affects and is affected by other things. An optics or photonics specialist is the name given to someone who has expertise
Robert Bunsen and Niels Bohr. The discovery of Fraunhofer lines was based on earlier work in the field of optics, and lead to many discoveries in astronomy, chemistry, and physics. In 1604, Johannes Kepler published the book Astronomiae Pars Optica. The book has been considered by many to be the basis of all modern optics. In his research, Kepler discovered many of the fundamental principles of optics (Molecular Expressions). He discovered how the eye bends light in order to form an image. He was one
Polarization Introduction: PART ONE: POLARIZATION Method 1: Two polarized disks were put into a grooved holder with their polarization axes lined up, and a bright red light emitting diode (LED) was placed on one side, and a light sensor was placed on the other side. Light intensity was measured as a function of the plastic rotating polarizer angle from 0 to 180 degrees. Science Workshop was used to measure the intensity for every 5-degree rotation (Fig 1). Method 2: The mineral calcite
Investigating the Speed of Water Waves Introduction In this experiment I will be investigating the wave speed, of waves on water in a tray, and how this speed is affected. Waves can be longitudinal, when the particles move in the same direction as the direction of the wave, or it can be transverse, when the particles move at 90o to the direction of the wave. Water waves are transverse waves even though transverse waves cannot travel through liquid. This is because the waves travel
at the age of 75 in Syracuse. It is said that he was killed by a Roman soldier, who was offended by Achimedes, while the Romans seized Syracuse. Archimedes had a wide variety of interests, which included encompassing statics, hydrostatics, optics, astronomy, engineering, geometry, and arithmetic. Archimedes had more stories passed down through history about his clever inventions than his mathematical theorems. This is believed to be so because the average mind of that period would have
At the University, he studied both physics and medical physiology. There, his doctoral teacher was Andreas von Ettingshausen. Mach received his doctorate in physics in the year 1860. Earlier his work was composed of working on the Doppler Effect in optics. After receiving his doctorate, Mach went on to teach mathematics as a professor at the University of Graz. He was a doctoral advisor to Heinrich Gomperz, another austrian physicist. Although he was teaching mathematics, his interests were still with

Isaac Newton’s Prism Experiment Theories should be tested, and have efficient evidence in order to be considered as scientific. Isaac Newton’s prism experiment was a critical experiment in the physics community where Newton researched and tested white light to isolate the explain that white light was made of several colours of light. In Newton’s day, colour was stated as being a mix of light and darkness, and white light obtained colour by passing through prisms. The resulting colour would depend
CHAPTER 2 LITERATURE REVIEW 2.1 Introduction of photogrammetry Photogrammetry has been defined by the American Society for Photogrammetry and Remote Sensing as the art, science, and technology of obtaining reliable information about physical objects and the environment through process of recording, measuring, and interpreting photographic images and patterns of recorded radiant electromagnetic energy and other phenomena. Even though photogrammetry has expanded to include analysis of the other
The refractor telescope is a telescope that uses lenses and refraction in order to magnify images. Light travels in a wave with differing speeds. A medium (or media) is any one type of transparent matter e.g. Air, Glass, Water or a lack of matter (A vacuum) . The optical density of a medium is the amount that it slows light down when light is passing through it .This means light travels at different speeds in different mediums Because of this the light wave will refract (bend) when it passes from
What is a silver sparrow? The term was invented by Tayari Jones, who was in search of a new title for her novel. The word “silver” refers to girls that are naturally beautiful and have no need for makeup. The term “silver girl” comes from a classic Simon and Garfunkel Song, “Bridge Over Troubled Water.” The lyrics are “Sail on silver girl,” which refers to Simon’s first wife who’s hair was beginning to become silver (Cohen 1). This unplanned third verse of the song gave Jones inspiration for her
The universe is vaster than we could ever image and seems the more we learn the more mysterious it becomes. Gazing through a telescope is a fascinating hobby that once started can last a lifetime. Today, we offer up a selection of 10 scopes that are suitable for beginner as well as the seasoned sky watcher. They cover the spectrum of features and any of them can fit into most budgets. Learning about the universe in which we live is an exciting hobby and one that you’ll find rewarding as well. So
In this report I will be explaining about lenses in medieval times and how Eyeglass, microscope and telescope lenses were created, used for and how they affected the growth of science and technology in a positive and negative way. I will also be discussing the short and long-term impacts of lenses and how these have influenced the economic and social developments of medieval times. Different Types of Lenses What are lenses? A lens is a piece of glass or other material with curved sides that concentrate
According to Merriam-Webster’s Dictionary, photography is defined as, “the art or process of producing images by the action of radiant energy and especially light on a sensitive surface (such as film or an optical sensor).” However, many question the validity of this statement around 190 years ago due to drastic technological differences. Personally, I see photography as a feeling rather than something easily defined. Despite the modern support affiliated with my claims, the original inventor of
Microscopy Summary The entire exercise was all about caring for and using the microscope. We performed various activities that enabled us to familiarize ourselves with the parts and uses of the microscope. Using the microscope, we observed different objects such as cotton, silk, hair, and even a letter "e." We viewed it using both the low power objective and the high power objective. We did these activities in order to better understand how the compound light microscope works and also to
Missing Figures Imagine this, you are walking through the forest when all of a sudden you come across the most fascinating insect (perhaps insects may not seem too fascinating at first but once you learn a little about them they are the most fascinating creatures). Well, back to the story, so you find this insect and you realize that it seems very different from those you've previously encountered. Well, being the curious scientist that you are, you take out your trusty magnifying glass and take
important contributions to many fields of science. His discoveries and theories laid the foundation for much of the progress in science. Newton was one of the inventors of a mathematics called calculus. He also solved the mysteries of light and optics, formulated the three laws of motion, and derived from them the law of universal gravitation. Newton was born on December 25, 1642, at Woolsthorpe, near Grantham in Lincolnshire. When he was three years old, he was put in care of his Grandmother
incredible in the fields of biomedical science, nanoengineering, and microscopy. The second topic of this paper, Microscopy, covers two methods of advanced microscopy that allow us to see much smaller than the optical limits allow. Plasmonics In optics, if a beam of light hits a boundary at a certain critical angle, all the light will be reflected back. In classical physics none of the light crosses the boundary, but is instead reflected back perfectly. If the light is viewed as a potential wave
Flow Visualisation using Shadowgraphy Technique Shadowgraphy is one of the optical techniques for observing a flow in a transparent medium. The basic apparatus consists of a light source and a recording plane onto which the shadow of the varying density field is projected. The technique is based on the variation in refractive index of the transparent media caused by density variation in the flow field. The experiment is carried out in the laboratory and density gradient is created by generating
Brenton Coon Jamie Vilos Info Lit 14 May 2014 METAMATERIALS THE “WAVE” OF THE FUTURE For decades film makers and science fiction authors have toyed with the idea of what technology will look like in the future. Be that tractor beams, space ships, holodecks, transporters and so on. Because of the amazing creativity of minds from the past we benefit from their ideas now in the present. Technologies such as cell phones, blue tooth, head’s up displays, touch screens and even sliding glass doors are
