Light of wavelength λ=5890Å fall on a double-slit arrangement having separation d=0.2mm. A thin lens of focal length f=1m is placed near the slits. The linear separation of fringes on a screen placed in the focal plane of the lens is In a YDSE with identical slits the intensity at the same point is the [...]
Two light waves having the same wavelength λ in vacuum are in phase initially. Then the first ray travels a path of length L1 through a median of refractive index μ1. The second ray travels a path of length L2 through a medium of refractive index μ2 . The two waves are then combined to observe interference effects. The phase difference between the two, when they interfere, is

A plane wave of monochromatic light falls normally on a uniform thin or oil which covers a glass plate. The wavelength of source can be varied continuously. Complete destructive is observed for λ=5000Å and λ=1000Å and for no other wavelength in between. If μ of oil is 1.3 and that of glass is 1.5, the thickness of the film will be
