Question

If the index of refraction for a certain glass is 1.50, and the angle of refraction is 15 degrees for a ray of light travelling from air, what is the angle of incidence? *

Answer 1

Answer:

The angle at which the light strikes the glass with incidence surface when a ray of light is passed through the glass is known as the angle of incidence. The angle at which light leaves the glass, is known as the angle of refraction. Snell's law is used for the analysis of the incident and refractive angles.
