Question

if the speed of light in the medium is 1.5 into 10 raise to power 8 metre per second what is the absolute refractive index of the medium

Answer 1

Answer : the absolute refractive index of the medium is 2

Explanation :

v = c / u

where c is the speed of light in vacuum

u is the absolute refractive index of the medium

and v is the speed of the light in that medium

So, u = c / v

       c = 3 x 10 ^ 8 m/s

       v = 1.5 x 10 ^ 8 m/s given

=> u = 3 x 10 ^ 8/ 1.5 x 10 ^ 8

       = 3 / 1.5

       = 2
