Q4 of 26 Page 1

For the same angle of incidence, the angle of refraction in two media A and B are and respectively. In which medium is the speed of light less?

As the angle of refraction is more in B, the refractive index would be less. So, A is a medium with higher refractive index().


The speed of light decreases by a factor of . So, the speed of light in medium A would be less as compared to B.
