Question

A ray of light is incident on a glass slab at a polarising angle of 58° calculate the % change in the speed of light in glass

Answer 1

Answer:Angle Of Incidence is always equal to Angle Of Reflection.

So Angle Of Incidence is 90°

Then Angle Of Reflection will be 90°

Explanation:Remeber the law that : Angle Of Incidence is always equal to Angle Of Reflection.

So Angle Of Incidence is 90°

Then Angle Of Reflection will be 90
