The width of one of the two slits in Young's double slit experiment is d while that of the other slit is \(x\mathrm{d}\). If the ratio of the maximum to the minimum intensity in the interference pattern on the screen is \(9:4\) then what is the value of \(x\) ?
(Assume that the field strength varies according to the slit width.)
