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.
Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.
Snell's Law provides the quantitative means of answering the question of "By how much does the light ray refract?" The task of answering this question involves using indices of refraction and the angle of incidence values in order to determine the angle of refraction.
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.
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.
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.
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.
