Question

2) The refractive index of water is 4/3 and the
speed of light in air is 3 x 10° m/s. Find the
speed of light in water.​

Answer 1

Answer:

refractive index of water=4/3 so speed of light in water is 2.25 10 m/s

Answer 2

Explanation:

speed of light in water x km/hr.(say)

A/q-

3×10^8/x=4/3

x=9/4×10^8

x= 2.25×10^8km/hr.
