List of top Physics Questions on Reflection Of Light By Spherical Mirrors asked in NEET (UG)

When light propagates through a material medium of relative permittivity єr, and relative permeability єr, the velocity of light, v is given by (c - velocity of light in vacuum)

The angle of a prism is A. One of its refracting surfaces is silvered. Light rays falling at an angle of incidence 2A on the first surface returns back through the same path after suffering reflection at the silvered surface. The refractive index p, of the prism is

Two plane mirrors are inclined at 70$^{\circ}$. A ray incident on one mirror at angle, $\theta$ after reflection falls on second mirror and is reflected from there parallel to first mirror. The value of $\theta$ is
