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

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).

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

The fringe width in Young’s double slit experiment increases when

If the width of the slit S in Young's double slit experiment is gradually increased
