Question

A ray of light enters one face of the prism at an angle of incidence of 40 & emerges at an angel of 50 if the devotion in the ray is 30degree, Then angle of prism is ​

Answer 1

Explanation:

Angle of prism is A=30

o

,

Angle of incidence is i=60

o

,

Deviation is δ=30

o

,

Let angle of emergence be e ,

For prism relation between them is given by ,

δ+A=i+e,

putting the values we get,

30+30=e+60

∴e=0

Angle of emergence is 0.

Answer 2

Answer:

Angle of emergency is 0 hope it helps u keep smiling :)
