Question

Explain about refractive index

Answer 1

the refractive index of second medium with respect to the first medium is defined as the ratio between the sine of the angle of incidence in the first medium to the sine of the angle of refraction in the second medium

Answer 2

Heya!!
The extent of the change in direction that takes place in a given pair of media is expressed in terms of the refractive index

1mu2 represents refractive index of medium 2 with respect to medium 1 when light is going from medium 1 to medium 2

=) 1mu2 = mu2/ mu1 = sin i / sin r

to understand and to now the better im giving u a facts
facts - refractive index of air is minimum and refractive index of diamond is maximum


hope this helps u
