PHYSICS INTERNAL ASSESSMENT By: Salman Charolia For the coffee filter paper, how does the mass, by adding items such as paper clip, affect the time for the coffee filter to fall from an initial height? Design: Problem: For the coffee filter paper, how does the mass, by adding items such as paper clip, affect the time for the coffee filter to fall from an initial height? Hypothesis: If the mass is increased then the time for the filter paper to fall will decrease because there is more force occurring
store digital data has been around for many years, and its promises have long been apparent. Holograms are recorded by intersecting an image bearing laser beam with a reference beam. The intersection of these beams records the image into the medium which is being recorded on, and the image can then be read later by shining a reference beam at the laser, which then "reproduces the original image-bearing wavefront" (Heanue, Bashaw, and Hesselink 749).
Laser is an acronym used for Light Amplification by Stimulated Emission of Radiation. Laser treatment is a procedure used to cure skin problems with a strong beam of light. Experienced cosmetologists and dermatologists use this new technology to cure many ailments. Side effects of laser treatment: Several side effects can be experienced with acne blemish laser treatment like irritation, redness and swelling on the affected areas. These side effects persist only for a few hours or a day. In certain

Gordon Gould proposed laser action, then not long after 4 years, in 1960, first laser was build by Theodore Maiman. Besides that, Gordon also derived the word laser from “light amplification by the stimulated emission of radiation”. The laser developer look amplification is very important as a step to build a laser, so these people make one advance to develop amplifiers from semiconductor laser to be used as light sources. This is because of semiconductor have high gain. Laser made up with high gain
Birth of the Universe Your universe, as we have suggested many times, as we've suggested already this morning, is but one universe among many. It is relatively a small universe — not to suggest that you should feel badly … {laughter} … for despite the consensus reality that bigger is better, despite the male-dominating energy and the comparative energies that say "bigger is better," your universe, though relatively small, is not at all diminished by its size. Now we know the word universe by
is to inform the reader of all the things that take place when you watch a movie on a DVD player, starting with the CD itself. The laser reads the CD and converts it to the final product of what we see and hear. Most CDs are made from polycarbonate plastic. This polycarbonate is a tough material that helps to prevent scratching. Scratching of a CD causes the laser, which reads the spiral data, to jump off track, allowing the CD to skip around and to distort whatever you are watching or listening
the richest and most powerful nations on the world. Since we are so strong, many countries threaten us and endanger the citizens. Lately, a system called the Star Wars SDI was initialized during the Reagan Administration. The system involves lasers that will fry the chips in missiles. That will cause the missile to stop in its flight and not detonate. Now, it is being researched again. But even though the Star Wars system seems flawless, it shouldn^t be employed. The system uses up a
Christopher Lathrop: Autobiography My name is Christopher Ray Lathrop. And this is my Auto biography. I was born at Saint Peters Hospital right here in Olympia WA. Where my other two brothers Jarred 15, and Ryley 20 months, were born as well. I traveled to Michigan with my family, when I was around seven or six. Where my Aunt lives with her six kids and a small Korean family. I remember my mother gave my brother and I ,what she refereed too as a Care Package, Right before the trip. It was filled
The laser is one of the most advanced tools we have in our civilization. Lasers are powerful enough to cut through a thick piece of steel, yet can be used in medical surgery. Lasers are used in the army, for guns, for range finding and a whole lot more. Most people don't know where the idea of the laser came from. The idea for the laser came from a machine called a maser. The maser was a tool that was able to strengthen, or amplify radio and light waves. The first laser was made in California
so we can place tracks very close together, and the size of the track we use is dependent only on one thing - the color of the light we use. An optical medium typically involves some sort of laser, for laser light does not diverge, so we can pinpoint it to a specific place on the disk. By moving the laser a little bit, we can change tracks on a disk, and this movement is very small, usually less than a hairÕs width. This allows one to store an immense amount of data on one disk. The light does
“SHHHH…!” Harper awoke to the sound of hushed giggles in the dorm. In the moonlight she could see that the older girls across the room were dressed like they were about to go dancing with boys. Harper squinted her eyes as they opened the door and the harsh light from the hallway flooded in. She looked over at Saskia’s bed. Saskia had turned away from the door with the covers pulled up over her, she was either asleep or pretending to be. Harper suspected she was pretending. The girls let out a final
aircraft by using Global Positioning Satellites, which constructs coordinates and data collected. The green laser is used due to its incorporation of light in murky waters is the slightest at these wavelengths. One laser is applies which creates an infrared laser. A frequency double then changes the frequency of a fraction of the beam by a aspect of two , resulting in a green light laser. Some Advantages and Disadvantages of LADS include: Advantages Disadvantages ? A quick and effortless
Introduction In the world of communication, lasers can be very helpful in transporting a variety of information across the planet. In this experiment, we decided to advance our knowledge about lasers and perform more tedious activities with them. Instead of shooting lasers through a gelatin substance and reading angles in which they reflect, we were going to step it up a bit. This time our final goal was to be able to verbally communicate through space using a laser. Photonics is described as science and
How do they know how fast we are going? Speed determination is accomplished in two basic ways. First, the least sophisticated method is dependent upon an officer's ability to guess your speed. Second, either some electronic method using radar or laser instrumentation authenticates that officer's guess. As you will see, their guesses are usually right on target. What does this mean for you? Usually a speeding ticket or if your infraction isn't a flagrant disregard for safety, a friendly warning
aliens in the movie in the movie make weird noices that have to be translated at the bottom of the screen. Another common sound effect used in the movie is lasers. Lasers are used in the fight scenes that take place with the space ships. The sound effects of the ships themselves are incredible and the sound when they get hit get hit by a laser really grabs the attention of the viewer. Other sound effects include the sound of the light sabers that Luke Skywalker and Darth Vader use. They make a vibrating
James T. Russell and the Invention of the Compact Disc James Russell was born in Bremerton, Washington in 1931. His first invention, at six years old, was a remote-control battleship with a storage chamber for his lunch. In 1953, he earned his Bachelor of Arts in physics and graduated from Reed College in Portland. Afterwards he went to work as a Physicist in General Electric's nearby labs in Richland, Washington. There he started many experimental instrumentation projects. He was one of
Holographic Universe In autumn of 1992, one of the world's greatest contemporary physicists passed away. David Bohm, whose work inspired many people all over the world, died in London. David Bohm's contributions to science and philosophy are profound, and they have yet to be fully recognized and integrated on the grand scale. David Bohm was born on December 20, 1917, in Wilkes-Barre, Pennsylvania. Bohm was fascinated by the dazzling concepts of cosmic forces and vast expanses of space that
manufacturing and processing techniques especially the Selective Laser Sintering (SLS), which could easily make complex geometries directly from digital CAD data. Because of my excellent performance and great enthusiasm, Prof. Yusheng Shi, a leading expert in addictive manufacturing, accepted my application to join his laboratory when I was a sophomore. I teamed up with four senior students, aiming to improve the system of selective laser sintering. We designed CAD models and made theoretic analysis
University March 8 2014 Working around heavy machinery and equipment is part of everyday life for many people around the world in many different types of occupations and industries. Machines like forklifts, overhead cranes, conveyor belts, laser cutters, and almost anything else imaginable can cause harm or injury if not used properly. These machines are often extremely powerful and heavy, but most importantly they are totally unforgiving when it comes to human error. The problem starts when
