Question

From Snell's law, the angle of refraction is determined in terms of
h
Angle of incidence
Refractive index
Angle of deviation
Both a and b​

Answer 1

Answer:

According to Snell's law, the angle of refraction, θr, depends on the angle of incidence, θi, and the ratio of the refractive indices of the two media that make up the interface. ... Similarly, light that enters the interface normal to its surface is not deviated, because θi=0° and sin θi=0 and therefore θr=0° by Eqn [4.8.

Answer 2

Answer:

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.
