A slab of glass with an index of refraction of 164 is

Question

Compute all parts of given question:

Question: A slab of glass with an index of refraction of 1.64 is submerged in a liquid with an index of refraction of 1.27. Light in the liquid is incident on the glass.

Part A: Find the angle of refraction for the angle of incidence of 60°.

Part B: Find the angle of refraction for the angle of incidence of 45°.

Part C: Find the angle of refraction for the angle of incidence of 30°.

Please explain and show work so I can do it next time!
