Question

The refractive index of water is 1.33.the speed of light will be​

Answer 1

Answer:

Explanation:Refractive index = Speed of light in vaccum / Speed of light in water. It is denotes as n = c / v, v = c / n= 3 × 10^8 m/s / (1.33) = 2.25 × 10^8 m/s. Therefore, refractive index of the water can be measure by the Speed of light in water is 2.25 × 10^8 m/s.

Answer 2

Answer:

2.25 *10^8

Explanation:

Refractive Index = speed of light in water / speed of light in vaccum

=> n= c/v

=> 1.33 = 3 * 10^8 / v

=> v = 3* 10^8 / 1.33 = 2.25 * 10^8 m/s
