Physics - Sound Wave Question with Solution | TestHub

Consider two coherent, monochromatic (wavelength$\lambda$) sources,${\mathrm{S}}_1$and${\mathrm{S}}_2$, separated by a distance$d$. The ratio of intensities of${\mathrm{S}}_1$and that of${\mathrm{S}}_2$(which is responsible for interference at point$\mathrm{P}$, where detector is located) is$4$. The distance of point$\mathrm{P}$from${\mathrm{S}}_1$is (if the resultant intensity at point$\mathrm{P}$is equal to$\frac{9}{4}$times of intensity of${\mathrm{S}}_1$) (Given:$\mathrm{\angle }{\mathrm{S}}_2{\mathrm{S}}_1\mathrm{P}=90°$,$d>0$and$n$is a positive integer)
