Question

The refractive index of a prism is 2. This prism can have a maximum refracting angle of

Answer 1

If the refractive index of a prism is 2, its maximum refracting angle is of 60 degree

Answer 2

Every prism is a type of equilateral triangle whose refracting angle should be 60° ..
So the R.I. of a prism is 2 then the maximum refracting angle is 60°....
