The critical angle between an equilateral prism and air is

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
