Question

reflective index:
(a) depends on the wavelength of light used
(b) is the actual property of the medium
(c) depends on the angle of incidence
(d) none of the above ​

Answer 1

Answer:

In optics, the refractive index of a material is a dimensionless number that describes how fast light travels through the material. It is defined as n={\frac {c}{v}}, where c is the speed of light in vacuum and v is the phase velocity of light in the medium.

Explanation:

option b is correct
