In the Young's double slit experiment, the intensities at two points \(P_1\) and \(P_2\) on the screen are respectively \(I_1\) and \(I_2\). If \(P_1\) is located at the centre of a bright fringe and \(P_2\) is located at a distance equal to a quarter of fringe width from \(P_1\), then \(\frac{I_1}{I_2}\) is
- A 2
- B \(\frac{1}{2}\)
- C 4
- D 16
Answer & Solution
Correct Answer
(D) 16
Step-by-step Solution
Detailed explanation
Fringe width \(\beta=\frac{\lambda D}{d}\) Let the amplitude of that place where constructive inference takes place is \(a\). The position of fringe at \(p_2\) is \(x=\frac{n \lambda D}{d}\)…
