Question

If the speed of light in water is 2.25* 108 m/s and in air it is 3.00*108 m/s. if a ray of light passes from air to water at an angle of incidence of 300 calculate the angle of refraction

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
