Question

give the relation between angle of incidence, angle of emergence, angle of deviation and Angle of prism

Answer 1

Heya,
Good question,
Now lets unlock the answer

______________

Angle of Deviation = (Angle of incidence) + (Angle of emergence) - ( Angle of Prism)

This is for a prism, without using any special conditions.

A special condition arises, when you want the minimum angle of Deviation. Then the equation becomes:

Angle of Deviation = 2(Angle of incidence) - ( Angle of Prism).

Hope you understood.
