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 \(1: 1\)
- B \(9: 1\)
- C \(2: 1\)
- D \(3: 1\)
Answer & Solution
Correct Answer
(C) \(2: 1\)
Step-by-step Solution
Detailed explanation
The intensity \(I\) of a wave is proportional to the square of its amplitude \(A\), so \(I \propto A^{2}\). Let the amplitudes of the two coherent sources be \(A_{1}\) and \(A_{2}\). The maximum intensity \(I_{max}\) and minimum intensity \(I_{min}\) are given by the relations…
