Question

The refractive indices of water for red and violet colours are 1.325 and 1.334 respectively. Find the difference between the velocities of rays for these two colours in water

Answer 1

Answer:

Explanation:

RELATION BETWEEN REFRACTIVE INDEX AND VELOCITY.

R1/R2=V2/V1

1.325/1.334= V2/V1

0.99=V2/V1

V2= 0.99V1

DIFFERENCE= V1-V2

                      =   V1-0.99 V1

                      = 0.01 V1.
