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.

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.

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 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 of light is incident normally on one of the faces of a prism of angle 30^@ and refractive index sqrt2 . The angle of deviation of the ray is

A prism of refractive index sqrt(2) has refractive angle 60^(@) . Find the angle of incidence so that a ray minimum deviation.

A prism of refractive index sqrt(2) has refractive angle 60^(@) . Find the angle of incidence so that a ray minimum deviation.

A ray of light is incident normally on one of the faces of a prism of angle 30^@ and refractive index sqrt 2 . The angle of deviation of the ray is

A ray of light is incident on the surface of a sphere of refractive index sqrt(7)/(2) other half of sphere is silvered. After refraction it is reflected and then refracted out of sphere again such that the total deviation is minimum then total deviation of the ray will be (sin41_(0)-sqrt((3)/(7)))
