Question

The speed of light in medium A is 2x108 m/sand speed of light in medium B is
2.5 x108 m/s. Calculate the refractive index of medium B with respect to
medium A

Answer 1

Explanation:

This is the concept . you can change the values accordingly

speed of light =speed in vacuum/refractive index

2x10^8=speed in vacuum of light/1.5

speed in vacuum of light=3x10^8m/s

now

speed in medium A=speed in vacuum/refractive index

=3x10^8/2=1.5x10^8m/s
