Question

The relation between angle of incidence, angle of emergence, angle of deviation and
angle of prism is given as...
A d=(i1=i2)
B. A+d=i11-i22
CA+d=i1+i2
DA-D=i1+i2​

Answer 1

Answer:

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.

#So,i + e=A + δ

this is relation
