A prism of angle 60^@ deviates a ray of light through 32^@ for two angles of incidence which differ by 12^@ . The angles of incidence are

For a ray of light refracted through a prism of angle 60^(@) , the angle of incidence is equal to the angle of emergence, each equal to 45^(@) . Find the refractive index of the material of the prism.

For a ray of light refracted through a prism of angle 60^(@) , the angle of incidence is equal to the angle of emergence, each equal to 45^(@) . Find the refractive index of the material of the prism.

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 .

(a) If the refracting angle of a prism is 60^@ and the minimum deviation is 30^@ , then find the angle of incidence. (b) A ray of light passes through an equilateral prism such that the angle of emergence is equal to the angle of incidence and each is equal to 3//4^(th) of the angle of prism. Find the angle of deviation. (c) The refracting of a prism is A and the refractive index of the material of the prism is cotA//2 . Find the angle of deviation. (d) The angle of a prism is 60^@ . What is the angle of incidence for minimum deviation? The refractive index of the material of the prism is sqrt2 .

The angel of incidence for a fay of light at a refracting sufrace of a prism is 45^(@). The angle of prism is 60^(@) If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism repectively, are
