Refraction through glass slab experiment and verification of Snell’s law. Abstract: The graph-1 shows a linear relationship; the greater the angle of incidence, the greater the angle of refraction.
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 n 1 sinθ 1 = n 2 sinθ 2 or n 1 sinθ i = n 2 sinθ t Here, n 1 and n 2 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. In this
Snell’s Law provides the relation between the angles of incidence and of refraction: n 1 sin(θ 1 )= n 2 sin(θ 2 ) where n 1 and n 2 are the indexes of the refraction of the two materials light travel through.
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. In this experiment you will investigate the process of refraction and determine the index of refraction of a material.
