μ21=speed of light÷speed of medium
=3x10^8÷1.4x10^8→2.14

Nishant5001: is it correct

Nishant5001: can u plz give me more clearly plzz

payal891: and state the laws of refraction of light

Nishant5001: ok that one i will give u

Nishant5001: is 2.4 is correct answer?

Nishant5001: plz say is it correct

Answered by Nishant5001

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

2)the ratio of sine of angle of incidence to sine of angle of refraction is constant for a given pair of medium

2M1=(speed of light in vacuum )/(speed of light in medium)

=>(3×10^8)/(1.4× 10^8)
=>2.14
