Physics - Wave Optics Question with Solution | TestHub

In a Young's double slit experiment, the intensity of light at a point on the screen where the path difference between the interfering waves is $\lambda$, ( $\lambda$ being the wavelength of light used) is $\mathrm{I}$. The intensity at a point where the path difference is $\frac{\lambda }{4}$ will be (assume two waves have same amplitude)
