Explain the Young's double slit experimental setup and obtain the equation for path difference.

If young's double slit experiment is performed in water

In Youngs double slit experiment, to increase the fringe width

A Young's double slit experiment is performed with white light.

In Young's double slit experiment light waves are coherent. Why?

In a Young's double slit experiment, the intensity at a point where the path difference is (lamda)/6 ( lamda - wavelength of the light) is 1. If I_(0) denotes the maximum intensity, then I/(I_(0)) is equal to

When we close one slit in the Young's double slit experiment, then

In Young's double slit experimental set up, it the wavelength alone is doubled the band width beta becomes,

Find the intensity at a point on a screen in Young's double slit experiment where the interfering waves of equal intensity have a path difference of lamda/4

Find the intensity at a point on a screen in Young's double slit experiment where the interfering waves of equal intensity have a path difference of lamda/3

What is the effect on the interference fringes in a Young' double slit experiment due to each of the following operations. a. the screen is moved away from the plane of the slits. b. the (monolchromatic) source is replaced by another (monochromatic) source of shorter wavelength. c. the separation between the two slits is increased. d. the source slit is moved closer to the double slit plane: e. the width of the source slit is increased. f. The monochromatic source is replaced by a source of white light? (in each operation, take all parameters, other than the one specified, to remain unchanged).
