Question

The refractive index of water is 4/3 and speed in air is 3 × 10^8 m/s. Find the speed of light in water ​

Answer 1

Answer:

2.25× 10^8 m/s

Explanation:

Speed of light in air

Refractive index = --------------------------------

Speed of light in water

4/3 = 3× 10^8/ Speed of light in water

Speed of light in water= 2.25× 10^8 m/s
