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).

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

In Young’s double slit experiment, the central bright fringe can be identified

In the Young's double slit experiment the central maxima is observed to be I_(0) . If one of the slits is covered, then intensity at the central maxima will become-

In Young's double slit experiment if wavelength of light is doubled without changing other conditions, the fringe width will

If the sodium light in Young’s double slit experiment is replaced by red light, the fringe width will

Young's double slit experimental arrangement is shown in figure. If lamda is the wavelength of light used and angleS_(1)CS_(2)=theta , then the fringe width will be

In the Young’s double slit experiment, for which colour the fringe width is least

If the separation between slits in Young’s double slit experiment is reduced to (1)/(3) rd, the fringe width becomes n times. The value of n
