Question

For the same angle of incidence of media A and B,C and the angle of refraction are 20•,30• and 40• Respectively in which medium will the velocity of light be maximum give reson on support of your answer

Answer 1

For a medium,

$\frac{sin \: i}{sin \: r} = \frac{n1}{n2} = \frac{v2}{v1}$

So, for a given angle of incidence(i) velocity of light is inversely proportional to sin r . So, more the angle of refraction less is the speed. So, order of speed of light will be A>B>C
