Question

Light travels with a velocity 3 x 〖10〗^(8 )m/s in a medium. On entering second medium its velocity becomes 2 x 〖10〗^(8 )m/s. What is the refractive index of second medium with respect to the first ?

​

Answer 1

Answer:

refractive index =1.5

Explanation:

C= 3×10^8 m/s

v= 2×10^8 m/s

refractive index n = c/v = 3×10^8/2×108=1.5
