Question

Velocity of light in air and in glass are 2.4 10 8 m/s and 2.14 10 8 m/s respectively. What is the refractive index of glass.

Answer 1

Answer:

1.12

Explanation:

c= 2.4 *10^8

v =2.14*10^8

n= c/v

n= 2.4*10^8/2.14*10^8

n=1.12

where c is speed of light in air

v is speed of light in glass

n is refractive index
