Question

The index of refraction of a substance is 1.5. Find the sine of the angle of refraction if the sine of the angle of incidence is 0.15.
sin r = _____

Answer 1

We can answer the problem by Snell's Law:

Snell's law (also known as Snell–Descartes law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.
