Question

2. The refractive index of water is 1.33 and the speed of light in air is 3x 108 ms-1. Calculate the speed of light in water.​

Answer 1

Speed of light in air(c) = 3 x 108; Speed of light in water =? ⇒ v= 2.25 × 108m/s. Hence speed of light in water is 2.25 × 108m/s.

Answer 2

Answer:

Speed of light in air(c) = 3 x 108; Speed of light in water =? ⇒ v= 2.25 × 108m/s. Hence speed of light in water is 2.25 × 108m/s.
