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)))`

A ray of light is incident on the surface of a glass plate of refractive index sqrt(3) at the polarising angle . The angle of refraction of the ray is

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 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 transparent sphere of R.I. mu = (sqrt(7))/(2) . After refraction is is internally reflected and refracted out of the sphere as shown in the figure. Find the angle of incidence 'I' so that the total deviation produced is minimum. 'C' is the centre of the sphere. .
