Problem 34.2: Find index of refraction, one medium

Please wait for the animation to completely load.

A light beam source, in air, is incident on a substance of unknown index of refraction. You can click-drag both the position and the ray angle of the beam. You can move the pink protractor around and use it to measure angles (position is given in meters and angle is given in degrees). Restart. What is the unknown substance?
