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 phase difference between the light waves reaching third bright fringe from the central fringe will be (lambda=6000Å)

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 light waves producing the third bright fringe from the central fringe will be ( lamda=6000 Å)

In the Young's double slit experiment, if the phase difference between the two waves interfering at a point is phi , the intensity at that point can be expressed by the expression

In Young's double slit experiment, the interference bright fringes are of:

In Young's double slit experiment, phase difference between the waves at a point on screen having intensity less than the average intensity on screen may be

In Young's double slit experiment, a third slit is made in between the double sits. Then

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
