In Young.s double slit experiment, what is the path difference between the two light waves forming 5th bright band (fringe) on the screen ?

In Young.s double slit experiment the phase difference between the waves reaching the central fringe and fourth bright fringe will be

In Young's double slit experiment, the phase difference between the two waves reaching at the location of the third dark fringe is

In Young's double-slit experiment, the path difference between two interfering waves at a point on the screen is 13.5 times the wavelength. The point is

In Young.s double slit experiment the band width is minimum for the colour

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

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

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

In a double slit experiment, at a certain point on the screen the path difference between the two interfering waves is 1/3 rd of a wavelength. The ratio of the intensity of light at that point to that at the centre of a bright fringe is:

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

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