The light beams of intensities in the ratio of \(9: 1\) are allowed to interfere. What will be the ratio of the intensities of maxima and minima?
- A \(3: 1\)
- B \(4: 1\)
- C \(25: 9\)
- D \(81: 1\)
Answer & Solution
Correct Answer
(B) \(4: 1\)
Step-by-step Solution
Detailed explanation
Hints: \(\frac{\mathrm{A}_1}{\mathrm{~A}_2}=\frac{3}{1}\) \[ \frac{I_{\max }}{I_{\min }}=\frac{16}{4}=\frac{4}{1} \]
