Question

If the speed of light in water is 2.25 x 10^8 m/s and the refractive index of air with respect to water is 1.33 find the refractive index of water with respect to water.​

Answer 1

Answer:

Speed of light in vacuum = 3.0×10

8

m/s

Speed of light in water = 2.25×10

8

m/s

Refractive index of water = ?

We know that

Refractive index of water =

Speed of light in water

Speed of light in vacuum

Refractive index of water =

2.25×10

8

3×10

8

=1.33
