A ray of light is incident on a concave mirror along its principal axis.What will be the angle of reflection?

A ray of light incident on a medium at polarising angle.what will be the angle between the reflected and the refracted rays? Or, an unpolarised ray of light is incident on a rectangular glass block at Brewster's angle. What will be the angle between the reflected and the refracted rays?

A ray of light is incident on a plane mirror at an angle of incidence of 30^@ . The angle of deviation as a result of reflection will be :

When a ray of light is incident perpendicularly on a transparent glass slab, what will be its angle of deviation?

If a converging beam of light is incident on a concave mirror, the reflected light

When a ray of light is incident on a plane normally, then what is the value of angle of refractive?

A ray of light is incident on a reflecting surface making an angle 50^(@) with the surface. Due to reflection, the angle of deviation is

The refractive index of a prism is sqrt(2) . A ray of light is incident on the prism grazing along one of its refracting surface. What should be the limiting angle of the prism for no emergent ray from the other face?

A ray of light is incident on a glass sphere and it makes an angle alpha with the normal, and then it is refracted at an angle beta . Calculate the angle of deviation between the incident and emergent ray.
