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 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
