The interference pattern is obtained with two coherent light sources of intensity ratio, n . In the interference pattern, the ratio, I max − I min I max + I min will be
Options
- An n + 1
- B2 n n + 1
- Cn n + 1 2
- D2 n n + 1 2
Correct answer
B. 2 n n + 1
Step-by-step solution
I 1 I 2 = n . I max = I 1 + I 2 2 = n + 1 2 I 2 . I min = I 1 - I 2 2 = n - 1 2 I 2 . I max - I min I max + I min = 4 n 2 n + 1 = 2 n n + 1
