Question

Light travels through water with a speed of 2.25 x 108

m/s. What is the refractive

index of water? Help me in this question..

​

Answer 1

Refractive Index = (3× 10^8)/(2.25 × 10^8)

= 3/2.25

= 1.33

Answer 2

Answer:

1.33

Explanation:

speed of light in vacuum/speed of light in given medium= refractive index

3*10tothepower8/2.25*10tothe power 8

1.333
