The refractive index of material of glass is 3 . If the angle of minimum deviation is equal to the angle of prism, the angle of prism is ( 30^ = 3 2 = 60^ , 30^ = 1 2 = 60^ )

Step-by-step solution

Given, = 3 and (60^ ) (30^ ) = 3 When light passes through a prism of refracting angle A, it suffers minimum deviation given by = ( A + 2 ) ( A 2 ) 3 = ( A + 2 ) ( A 2 ) A 2 =30^ and A + 2 =60^ are the solutions A=60^
