What will be the angle of incidence when a ray of light passes through the centre of curvature of a concave mirror?

What is the radius of curvature of plane mirror?

Show by ray diagram the formation of image of an object placed at the center of curvature of a concave mirror.

What will be the angle of emergence of a ray of light through a prism for an angle of incidents 45^(@) ? The angle of the prism = 60^(@) , refractive index of the prism = sqrt2 .

What is the angle of incidence when light passes from vaccume to a medium of refractive index sqrt3 ? Angle of refraction is 30^@ . What is the angle of deviation in this case?

The refractive index of a medium with respect to air is sqrt2 . If the angle of incidence of a ray of light in air is 45^@ determine the angle of deviation for that ray in case of refraction.

The angle of deviation of a ray of light refracted through a parallel glass slab is
