Question

Chapter 25: Problem 6: Suppose you have an unknown clear substance immersed in water, and you wish to identify it by finding its index of refraction. You arrange to have a beam of light enter it at an angle of 45.0⁰ with respect to the normal, and you observe the angle of refraction to be 40.3⁰. For convenience, the index of refraction for a variety of materials is provided below.

a) What is the index of refraction of the substance? 

b) What is its likely identity?
