38. Which law gives the relationship between a refractive index of the dielectric?

A. Law of reflection
B. Law of refraction (Snell's Law)
C. Millman's Law
D. Huygen's Law

Answer & Explanation

Answer: Option B

Explanation:

Snell's Law of refraction states that the angle of incidence Ã˜1 and refraction Ã˜2 are related to each other and to the refractive index of the dielectrics. It is given by- n1sinÃ˜1 = n2sinÃ˜2 where n1 and n2 are the refractive indices of two mediums. Ã˜1 and Ã˜2 are angles of incidence and refraction.
