Light in a vacuum is incident on a transparent glass slab. The angle of incidence is 40.6°. The slab is then immersed in a pool of liquid. When the angle of incidence for the light striking the slab is 11.7°, the angle of refraction for the light entering the slab is the same as when the slab was in a vacuum. What is the index of refraction of the liquid.© BrainMass Inc. brainmass.com October 24, 2018, 7:43 pm ad1c9bdddf
This is a good example of determination of refractive index using Snell's Law.
Refraction of Light: Snell's Law
A flashlight on the bottom of a 3.73 m deep swimming pool sends a ray upward at an angle so that the ray strikes the surface of the water 1.82 m from the point directly above the flashlight. What angle (in air) does the emerging ray make with the water's surface?View Full Posting Details
