Light incidence on a sphere of refractive index `sqrt3` placed in a air as shown in Figure. Find the angle `(theta)`in degree between emergent ray and reflected ray.

A light ray is incident on a glass sphere of reflective index mu = sqrt3 at an angle of incidence 60^(@) as shown in Fig. Find the angles r, r^(') e and the total deviation after two refractions.

A ray is incident on a sphere of refractive index sqrt(2) as shown in figure. Angle of refraction of the ray inside sphere is 30^(@) if total deviation suffered by the ray is 30x^(0) , then find x.

A ray of light falls on a glass plate of refractive index mu=1.5 . What is the angle of incidence of the ray if the angle between the reflected and refracted rays is 90^@ ?

A ray incident at a point at an angle of incidence of 60^(@) enters a glass sphere with refractive index sqrt(3) and it is reflected and refracted at the farther surface of the sphere. The angle between the reflected and refracted rays at this surface is:

A ray of light incident on a glass sphere (refractive index sqrt(3) ) suffers total internal reflection before emerging out exactly parallel to the incident ray. The angle of incidence was
