Vedclass · Answer

(D) The resultant intensity $I$ at any point in an interference pattern is given by the formula: $I = I_1 + I_2 + 2\sqrt{I_1 I_2} \cos \delta$,where $\delta$ is the phase difference between the two waves.For maximum intensity,the phase difference $\delta$ must be an even multiple of $\pi$ (i.e.,$\cos \delta = 1$).Substituting $\cos \delta = 1$ into the equation:$I_{max} = I_1 + I_2 + 2\sqrt{I_1 I_2}$This expression can be written as the square of a binomial:$I_{max} = (\sqrt{I_1} + \sqrt{I_2})^2$.

Two coherent sources of intensities $I_1$ and $I_2$ produce an interference pattern on a screen. The maximum intensity $I_{max}$ in this interference pattern is:
