4 It is totally reflected from all the three sides of prism and never emerges out When light rays are incident on a prism at an angle of 45 the minimum deviation is obtained If refractive index of the material of prism is 2 then the angle of prism will be 1 30 2 40 3 50 4 60 fronting angle is 60 For minimum
