Physics - Wave Optics Question with Solution | TestHub

Two coherent light beams of intensity$\mathrm{I}$and$4\mathrm{I}$are superposed. If the maximum and minimum possible intensities in the resulting beam are${\mathrm{I}}_{\max }$and${\mathrm{I}}_{\min }$, then${\mathrm{I}}_{\max }-{\mathrm{I}}_{\min }=\mathrm{nI}$. Find the value of$\mathrm{n}$.
