A prism is made up of material of refractive index 3 . The angle of the prism is Ã… . If the angle of minimum deviation is equal to the angle of the prism, then the value of A is:
Options
- A30^
- B45^
- C60^
- D75^
Correct answer
C. 60^
Step-by-step solution
aligned & = 3 , _m=A & For prism = A+ _m 2 A 2 & 3 = A+A 2 A 2 & 3 = A A 2 3 = 2 A 2 A 2 A 2 & A 2 = 3 2 & A 2 = 30^ & A 2 =30^ A=60^ & aligned
