Question

A ray passing in medium A is incident on the interface separating media A,B making an angle 30° with the surface. The ray enters medium B making 60° with the boundary surface with of the medium A or B is optically denser find the angle of deviation and the refractive index of medium B with respect to medium A​

Answer 1

ans

if v1 and v2 is velocity of light in medium 1 and medium to respective

then n12 the the refractive index of medium with respect to medium to is given by

n=v2/v1=1/n21

now according to snell's law when light is incident on medium 1 with angle 1 and refractive medium 2 with angle are Dan relation between them is given by

sin/sin =n2/n1=v1/v2=n21

Explanation:

I hope it's help
