In a Young's double slit experiment, the separation between the slits is d, distance between the slit and screen is D(Dgtgtd). In the interference pattern, there is a maxima exactly in front for each slit. Then the possible wavelength used in the experiment are:

In Young's double-slit experiment, the separation between the slits is d, distance between the slit and screen is D (D gt gt d) , In the interference pattern, there is a maxima exactly in front of each slit. Then the possilbe wavelength(s) used in the experiment are

In Young's double slit experiment,the sepaation between the slit is halved and distance between the slits and screen is doubled.The fringe width is
