In Young's double slit experiment, the ratio of maximum and minimum intensities in the fringe system is \(9: 1\). The ratio of amplitudes of coherent sources is
- A 9 : 1
- B 3 : 1
- C 2 : 1
- D 1 : 1
Answer & Solution
Correct Answer
(C) 2 : 1
Step-by-step Solution
Detailed explanation
Assume, Young's double slit experiment, amplitudes corresponding to the sources \(S_1\) and \(S_2\) be \(a_1\) and \(a_2\) and intensities be \(I_1\) and \(I_2\) respectively. So, \(I_{\max } \propto a_{\max }^2\) and \(I_{\min } \propto a_{\text {min }}^2\)…
