Question

state the laws of refraction of light explain the term of solute Refractive Index of a medium and write an expression to relate it with the speed of light in vacuum​

Answer 1

Answer:

Laws of Refraction

1.Snell Law of Refraction

The ratio between the values of the sine of angle of incidence and the sine of angle of refraction for two given optical media is a constant quantity.

2.The incident ray, the refracted ray and the normal lie in the same plane at the point of incidence.

The value of refractive index so obtained is called absolute refractive index.

Absolute refractive index = speed of light in vaccum/speed of light in optical medium

Explanation:

Answer 2

Explanation:

Laws of refraction -

1. The incident ray, refractive ray and the normal all lie on the same plane.

2. The ratio of sin of angle of incidence to sin of angle of refraction is constant for a pair of given media
