The law is used in ray tracing to compute the angles of incidence or refraction, and in experimental optics to find the refractive index. In this experiment we can determine the bending of light rays owing to the change in refractive index and hence verifying the law.
The objectives of this experiment are as follows: To measure the angles of incidence and refraction at a boundary between media. To observe total internal reflection at a boundary between media. To calculate the critical angle of a boundary between media.
Lab 10: Snell’s Law and Refraction. • Gain understanding about the behavior of light as it passes from one medium to another. • Compare least time travel to the rules of refraction. • Use Snell’s Law to calculate the index of refraction of water and compare it to 1.33.
Law of refraction. Snell's law relates the angle of incidence to the angle of refraction. Snell's law is stated as. n1sinθ1 = n2sinθ2 or n1sinθi = n2sinθt. Here, n1 and n2 refer to the indices of refraction of the two materials or in other words their optical densities. The index of refraction in air is n. air. = 1.00.
The objective of this experiment is to use Snell's law to determine the index of refraction of a glass plate. We will be measuring the angles of incidence and refraction and substituting into Snell's law to solve for the index of refraction of glass. In addition, we will be measuring various lengths in order to demonstrate the utility of the sine
In refraction we will learn that the angle of the ray when transmitted through the material changes and depends on the speed of light in the two materials. Many phenomena encountered in our daily lives can be simply explained on the basis of refraction and reflection.
In this experiment you aim a beam of light so that it moves through one transparent medium into another. When light passes from one material into another its direction of travel generally changes. This bending process is called refraction. The amount of bending depends on the properties of the media.
