Question

3×10^8/1.5
with explanation ​

Answer 1

Explanation:

The refractive index of a medium a with respect to vacuum is n=c/v (where c is the speed if light in vaciuum and v is the speed of light in medium a .

Here, n=1.5 , c=3 * 10^8 .(n is the refractive index of medium glass with respect to vacuum.)

v=c/n

v=(3*10^8)/1.5

v=2*10^8
