The critical angle between an equilateral prism and air is 45 If the incident ray is perpendicular to the refracting surface then 1 After deviation it will emerge from the second refaracting sufrace 2 It is totally reflected on the second surface and emerges out perpendicularly from third surface in air 3 It is totally reflected from the second and third refracting surfaces and finally emerges out from the first surface 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
