Before you read this description on Light rays and how they bend with the different densities and materials, I bet you want to know why you would bother to read this paper on a topic that at the moment you may not be overly interested in. Well here is the answer, With this information you can bend the wifi signal so that you can have the best wifi on the planet, starting to get more interested? Good, that is was my goal. Anyway, for this experiment, we used an online platform to simulate light rays using prisms, H20, Air and Glass. Using this program we measured the intensity of the reflection and refraction of light. We measured the angles of the vertical entry, The entry speed, and the various wavelengths from the different perspectives.Our Hypothesis was that if we shine light at various transparent objects of varying densities that the light would bend at a more significant angle as it moved through an object of a greater density.This was our procedure, We started off by digitally shining a light ray through several prisms (e.g. Triangles, Squares, Trapezoids, Circles, Convex and Concave), We noticed that different wavelengths of light (i.e. Colours of light) behaved differently, Some of them refracted at a sharper angle than the others had. Having done this, we discovered that an object with a higher density (glass) …show more content…
When we tried shining the light ray from Air into water the angle would pivot and would bend itself downward, but it had the opposite effect when we did it the other way round, so when we tried shining it from water to air the difference was that the angle of the light that was coming out of the water was pointing down as opposed to up as the other had done. The glass had the most impact on the angles, than it was the water and finally the air. Overall for this test we found that the density is a huge part of experiment as a

Geometrical Optics: Snell's Law PHY101 Lab 12 Date: July 23rd, 2012 Objective: The purpose of this laboratory activity is to develop a set of experimental procedures that answer questions regarding Snell's Law and the index of refraction. Ultimately, the experimental procedures you develop will allow the index of refraction to be found for water and cooking oil. 1. Explain how to experimentally determine the index of refraction of two substances. 2. Develop a set of experimental…

Nt1310 Unit 1 Lab Report

Two other examples of reflection is when you can see yourself in a bubble and also when light reflects of of snow or glitter Station 1B: Bubbles 1.We can see different colors in the bubble because the bubble is catching light waves that are in the visible light category which also contains colors. 2.In the bubble I can see everything around me just like a mirror. 3.We can see our…

Electromagnetic Radiation Lab

This lab was to test the change of heat of the water by burning a chip. The energy in the chip was the independent variable and the change in water temperature was the dependent variable. We first had to find the energy in the chip. We lit the chip on fire and found the temperature change in the water. We then had to design a calorimeter to try to improve the energy capture of what we had done before. Kinetic energy is the energy of motion and potential energy is energy due to an objects position…

Bunsen Burner Lab

The purpose of this lab is to conclude the identity of two unknown metals by observing the colors produced by the two groups of metals and a transition metal. When observing colors we only see a small spectrum, this is what we call the Visible Spectrum. The visible lights we can see are in a “wavelength range of 400 - 700 nanometers (nm)” and in a shade variety of “violet through red” (Madigan). The most dangerous colors are gamma rays, due to them being the highest in frequency and “most energetic…

Teacher: Ethanol and Gas Chromatography / Mass Spectrometry Essay

How Forensic Lab Techniques Work Forensic labs are often called in to identify unknown powders, liquids and pills that may be illicit drugs. There are basically two categories of forensic tests used to analyze drugs and other unknown substances: Presumptive tests (such as color tests) give only an indication of which type of substance is present -- but they can't specifically identify the substance. Confirmatory tests (such as gas chromatography/mass spectrometry) are more specific and can determine…

American Waterweed Experiment

sunlight to perform a process known as Photosynthesis ( 6CO2 + 6H2O + light energy = C6H12O6 + 6O2.), during this process plants use sunlight to synthesize foods from carbon dioxide and water. Without sunlight, most life on earth will suffer tremendously and a lot of life would even die off within the first few days. While light is usually a positive abiotic factor, different rays of light color effect plants differently. Most light that we see is combinations of wavelengths for optimal plant growth…

Ultraviolet Vision Essay

retina that respond to light, they are: rods, which mediate achromatic vision at low lighting and cones, which mediate chromatic vision at high levels of light. (Hoog et al., 2011) Rods, being sensitive to wavelengths, this enables them to be sensitive to low light levels but they do not produce a very high visual acuity. (Pough, 2009) There is a subgroup of cells within the cone cells of the retina that contain pigments that are highly sensitive to different wavelengths of light. Cone cells require…

Radiography Lab

type of lab test. It works by sending a small amount of radiation, at a specific wave length and special energy, which then passes through the body to a film cassette placed behind or under the body part being evaluated. The small amount of radiation makes the film cassette glow based on how much radiation gets through the body. The denser the material in the body, the lighter in color the film will be directly behind that area. For example, bone is very dense and will appear very light on the film…

Great Red Spot Research Paper

performing laboratory studies to investigate whether cosmic rays, one type of radiation that strikes Jupiter’s clouds, can chemically alter ammonium hydrosulfide to produce new compounds that could explain the spot’s color. Ammonium hydrosulfide is unstable under Earth’s atmospheric conditions, so Loeffler makes his own batch by heating hydrogen sulfide and ammonia together. He then blasts them with charged particles, similar to the cosmic rays impacting Jupiter’s clouds. “Our first step is to try to…
