Light enters from air into glass having refractive index 1.50. What is the speed of light in glass? The speed of light in vacuum is 3 x 108 ms-1.
Given,n=1.5 and the speed of light in vacuum, c = 3x 108 ms-1. We know that the refractive index is given by the expression n =c/v where c is the...

Why does white light split up into different colours while passing through a glass prism?
Light of different wavelengths (different colors) present in white light have different speed. Hence, these deviate through different angles inside the prism and get separated.

Let the resistance of an electrical component remain constant while the potential difference across the two ends of the component decreases
We know that, I=V/R Since the resistance remains constant, so the current is directly proportional to the potential difference. If the potential difference is halved, the current also gets halved.
