Question

(b) if the speed of light in vacuum is 3 x 10 m/s. Find the absolute refractive
index of a medium in which light travels with a speed of 1.4 x 108 m/s.
daharacteristics of the image formed by a plane mirror​

Answer 1

Answer:

Laws of refraction of light:

First law: The incident ray, the refracted ray, and the normal at the point of incidence all lie in the same plane.

Second law (Snell’s law): The ratio of sine of angle of incidence to the sine of angle of refraction is a constant for a given pair of media.
