Lab Report for Refraction.
Problem: What is the effect of density on the angle of refraction.
Hypothesis: The water will cause the light to refract more.
Background: Refraction is opposite of reflection where it bends the light and does not "bounce" it off of something. When light changes directions it must go through one medium to another at a specific angle to be bent. This bending is called refraction. Refraction causes our brains to be tricked and see an object not in its true position. This is because of how the light is bending. Light travels through different materials at different speeds. For example through air light travels at approximetely 300,000 kilometers per second. The speed of how fast light travels depends on the denisity

In other materials light travels in a straight line, it can reflect and refract. This depends on what surface it is enteracting with. For example when light collides with a mirror it bounce back in two different angles therefore it is not straight.
3. The three differences between the materials we used was that in one we had liquids in which we tested how the density effects the refraction of light. In a different one we had reflective surfaces where we tested how the path of light was affected with different angles of the reflective surface. The last thing was we had different measurements to be taken because we were looking for different things.
4. The container did affect the results a little bit. This is because instead of it going straight through the liquid it had to go through a denser material of plastic which altered the resulted minimally.
Conclusion: My hypothesis was supported because the water refracted the light more. This is shown by the diagrams and the angles being 30 and 41 .
Application: The law of refraction is used in everyday life by glasses. This is because lenses use the law of refraction to form an image of an object for example magnifying it. Another way we use the law of refraction daily is telesccopes. We use this in refraction because it changes the image by slowing down and bending the light rays to create a visible
3. The beaker was filled with water and the metal was placed in the water.
This is representative of how eutrophication works in an aquatic environment. It shows that the greater the number of blue-green algae then the faster the oxygen depletion
In this experiment, Newton placed a second prism 5 or 6 yards away from the first. At first, when the light passed through the prisms, his results were the same as the first experiment. However, when the prisms were moved farther away from the wall onto which the light was being projected, the light projected from the prisms became white again. When they were moved even farther, the light became colored again, but the color scale was inverted from the original scale. According to the accepted theory of light, the second prism changed the color of the light projected onto the wall. Therefore, Newton’s results once again contradicted the accepted theory of light. He also rotated the prisms to test if this would have an effect on the light, but it did not. Due to these observations, Newton concluded that light was in fact a combination of all light on the spectrum of light, not just a mixture of light and
Refraction is what happens to light when it passes from one medium to another. For example, things appear differently from the bottom of a swimming pool than on the top. Simplistically, refraction is the bending of light. The explanation for this phenomenon, however, can be described with light as rays and light as waves. No matter the case, it is important to remember that the speed of light is constant in every homogeneous medium, regardless of shape, size or form.
I will be talking about how images in a convex lens in a magnifying glass are affected by focal length. Concave lenses always produce virtual images because refracted rays do not intersecct. Images being reflected might change size depending on the material it is being reflected on. In some reflections it is common for an object to be reflected upside down because f the effect the material gives.
5. A second test tube was then filled with water and placed in a test
were to direct a beam of light at a glass block you will see that the
Shadowgraphy - an optical measurement technique is a field measurement method (image forming method) based on variation of refractive index in the flow field. The density of a fluid varies with temperature, salinity, and pressure. And, the index of refraction changes with fluid density. If a screen is placed opposite the light source, these effects create shadows on the screen creating an image called a Shadowgraph. The image ca...
Human eyes receive and form images from outside, also automatically changes in light and seeing things close up and at a distance. Therefore, we can see most of things from outside world. But without light, we can't see anything. Light travels though space and the sun gives off light rays then enter the eyes they are bent or refracted and these light rays create images or picture of all the objects around you, that's why we can see things very clearly. How light enter the eye, first light enters the eye though pupil which control different amounts of light into our eye. Then crystalline lens helps us see clearly, when we look at near objects crystalline lens will grows thicker and when we look at far objects then it will grows flatter. The crystalline lens and the cornea (the window of the eye) are bending light rays and sending them to the retinain the right direction. For our perfect vision, light rays must focus at one point on the retina.

...smits the waves from one direction but as soon as it reflects it blocks them from the other. [1]
The duality of how light behaves depends in which state light is being observed and how it interacts with an object 's surface. It is neither just a wave or a particle, they coexist and react to objects electrons and protons within their atoms. Animals, plants and our sky are examples of how light reacts and are seen.
Now in order to understand how lights is able to be refracted in different angles, it is important to understand the Snell’s Law which states that, the refractive angle always depend on the refractive index of both media. Now, the refractive index keeps on changing depending on the wavelength of the light passing through. Light, as we know, it is a wave that has different wavelength. Each wavelength represents a different color. Thus, different colors will have different refractive index when passed through the same media. It is important to note that light is normally refracted twice when it travels through a prism, first on its way in, and when it is going back.
The refracting telescope is one of many different types of telescope. Refracting telescopes work by refracting the light through an initial convex lens, (known as the objective lens), then through another convex lens (known as the eyepiece lens). These two lenses focus the light into the eyepiece so we can see the image clearly.
Light always goes in a straight line, however can change direction through reflection and refraction. Reflection occurs when a ray of light bounces off an object for example, a mirror. Refraction is where rays of light can go through a media and change direction for an example a lense or glass or the ozone layer. When light rays go through a median such as glass, some light refracts and some light reflects. As the rays enter the glass, they bend through the glass at a different angles and then exit at the same direction they entered.
