An electron in a hydrogen atom is considered to be revolving around a proton with a velocity (e^2)/(n) in a circular orbit of radius (n^2)/(me^2) . If I is the equivalent current, express it in terms of m, e, n.

A prism has refracting angle 30^(@) and mu = 2 . One of the mat surface of the prism is polished to make it reflecting. Find the incidence angle of a light ray on other mat surface of prism so that after reflection the ray will retrace the path of incident ray.
