Let `S_(1)` and `S_(2)` be the two slits in Young's double-slit experiment. If central maxima is observed at P and angle `/_ S_(1) P S_(2) = theta`, then fringe width for the light of wavelength `lambda` will be (assume `theta` to be a small angle)

If the two slits in Young’s double slit experiment are of unequal width, then

Let S_1 and S_2 be the two slits in Young's double slit experiment. If central maxima is observed at P and angle S_1 P S_2 = theta , ( theta is small) find the y-coordinates of the 3rd minima assuming the origin at the central maxima. ( lambda = wavelength of monochromatic light used).
