Eugene is given a clear material to identify. He shines a laser at the surface of the material at an angle of 25 degrees. The angle of the refracted ray is 16.7 degrees. Identify the clear material. Show how you arrived at this answer.
Calculate the index of refraction: sin(25)/sin(16.7) ≈ 1.47
This is the index of refraction of Pyrex.
