Question

The absolute refractive index of water is 1.36, what is the velocity of light in water ​

Answer 1

(velocity of light in vacuum 3 x108 m/s). Thus, V2 = 2.21×108 m/s. 10.

Answer 2

Explanation:

2.21×108 m/s.

Answer: We have, Velocity of light in vacuum (V1) = 3 x108 and n= 1.36 Now, suppose n = V1 / V2 Then, 1.36 = (3 x108) / V2 Therefore, V2= (3 x108) / 1.36 Thus, V2 = 2.21×108 m/s.
