In Young's double slit interference experiment, using two coherent sources of different amplitudes, the intensity ratio between bright to dark fringes is \(5: 1\). The value of the ratio of resultant amplitudes of bright fringe to dark fringe is
- A \(\left(\frac{\sqrt{5}+1}{\sqrt{5}-1}\right)\)
- B \(\sqrt{5}: 1\)
- C \(\left(\frac{\sqrt{5}-1}{\sqrt{5}+1}\right)\)
- D \(1: \sqrt{5}\)
Answer & Solution
Correct Answer
(B) \(\sqrt{5}: 1\)
Step-by-step Solution
Detailed explanation
\(\frac{I_{max}}{I_{min}} = \left(\frac{A_{max}}{A_{min}}\right)^2\) \(5 = \left(\frac{A_{max}}{A_{min}}\right)^2\)
