A monochromatic ray of light is incident normally on one of the refracting surfaces of a prism . The emergent ray grazes the second refracting surface . What is the angle of the prism if the refractive index of the material of the prism is 1.6 ?

A monochromatic ray of light is incident normally on one of the refracting surfaces of a prism . The emergent ray grazes the second refracting surface . What is the angle of the prism if the refractive index of the material of the prism is 1.6 ?

If the critical angle for the material of a prism is C, and the angle of the prism is A, then there will be no emergent ray when

If the critical angle for the material of a prism is C and the angle of the prism is A, then there will be no emergent ray when

A ray of light is incident on a prism of refracting angle A. if theta_(C) is the critical angle for the material of the prism with respect to the surrounding air, then:

A ray PQ incident on face AB of a prism ABC , as shown in Fig., emerges from the face AC such that AQ = AR . Draw the ray diagram showing the pasage of the ray through the prism. If the angle of prism is 60^@ and refractive index of the material of the prism is sqrt(3) , determine the values of angle of incidence and angle of deviation. .

The refractive angle of prism is A. A ray is incident normally on one of the refracting faces of a prism and emerges out. If D be the deviation of the ray then refractive index of the material of the prism is—

A ray PQ incident on the refracting face BA is refracted in the prism BAC as shown in the figure and emerges from the other refracting face AC as RS such that AQ = AR. If the angle of prism A = 60^(@) and the refractive index of the material of prism is 3, then the angle of deviation of the ray is
