Two coherent sources whose intensity ratio is \(64: 1\) produce interference fringes. The ratio of intensities of maxima and minima is
- A \(9: 7\)
- B \(8: 1\)
- C \(81: 49\)
- D \(81: 7\)
Answer & Solution
Correct Answer
(C) \(81: 49\)
Step-by-step Solution
Detailed explanation
The ratio of intensities of maxima and minima \(\frac{I_{\max }}{I_{\min }}=\frac{\left(\sqrt{I_1}+\sqrt{I_2}\right)^2}{\left(\sqrt{I_1}-\sqrt{I_2}\right)^2}\) \(=\frac{(\sqrt{64}+\sqrt{1})^2}{(\sqrt{64}-\sqrt{1})^2}\)…
