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.
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.
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.

Goals of the Experiment To study and observe the laws of reflection and refraction. To understand and practice optical ray tracing. To observe the operation of mirrors ...
Monochromatic light has a wavelength of 5.75 × 10% in air and 4.32 × 10% in a clear liquid. If a ray. of light enters this clear liquid at an angle of incidence of 25.0°, what is the angle of refraction? Answer –. 0.0× . = 1.3310. 1.× . 1.3310 × 1.0003. = 1.3314.
We learned that the angle of incidence is equal to the angle of reflection and the angles do not depend on the nature of the material. 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.
