Figure shows a standard two slit arrangement with slits $S_1, S_2. P_1, P_2$ are the two minima points on either side of $P \ ($Fig$)$. At $P_2$ on the screen, there is a hole and behind $P_2$ is a second $2- $ slit arrangement with slits $S_3, S_4$ and a second screen behind them.
An $AC$ source producing emf $\epsilon=\epsilon_{0}\Big[\cos\big(100\pi\text{s}^{-1}\big)\text{t}+\cos\big(500\pi\text{s}^{-1}\big)\text{t}\Big]$ is connected in series with a capacitor and a resistor. The steady$-$state current in the circuit is found to be $\text{i}=\text{i}_1\cos\Big[\big(100\pi\text{s}^{-1}\big)\text{t}+\phi_1\Big]+\text{i}_2\cos\Big[\big(500\pi\text{s}^{-1}\big)\text{t}+\phi_2\Big].$
