If two slits have width ratio 1 : 4. The ratio of maximum to minimum intensities in the interference pattern would be:
- A 1 : 4
- B 1 : 16
- C 9 : 1
- D 9 :16
Answer & Solution
Correct Answer
(C) 9 : 1
Step-by-step Solution
Detailed explanation
\(\frac{A_1}{A_2} = \sqrt{\frac{w_1}{w_2}} = \sqrt{\frac{1}{4}} = \frac{1}{2}\) \(\frac{I_{max}}{I_{min}} = \frac{(A_1+A_2)^2}{(A_1-A_2)^2} = \frac{(1A+2A)^2}{(1A-2A)^2} = \frac{(3A)^2}{(-A)^2} = \frac{9A^2}{A^2} = 9:1\)
