Question

light enters from air to water having tlrefractive index 4/3 . the speed of light in the water is ​

Answer 1

Answer:

speed of light in water = 2.25m/s

Explanation:

Refractive index = speed of light in air/speed of light in the medium

4/3 = 3×10^8/ s

4/3s = 3×10^8

s = 300000000×3/4

s = 750000000 ×3

s = 225000000 = 2.25×10^8 m/s

therefore, the speed of light in water will be 2.25×10^8 m/s.

Hope this will be helpful for u!!!!!
