Question

A ray of light passes through an equilateral prism such that the angle of incidence is equal to the angle of emergence and the latter is equal to 34th angle of prism. What will be the deviation?
  1. 450
  2. 370
  3. 200
  4. 30o

A
450
B
200
C
370
D
30o
Solution
Verified by Toppr

i=34A

Also i=A+δm2

A+δm2=34A

A+δm=1.5A

0r δm=A2=30o
