Describe Young's double slit experiment to produce interference pattern due to a monochromatic source of light. Deduce the expression for the fringe width.

State the importance of coherent sources in the phenomenon of interference. In Young's double slit expet-ment to produce interference pattern obtain the conditions for constructive and destructive interference. Hence deduce the expression for the fringe width. How does the firinge width get affected, if the entire experimental apparatus of Young's is immersed in water ?

Yellow light of wavelength 6000 Ã… produces fringes of width 0.8 mm in Young's double slit experiment. If the source is replaced by another monochromatic source of wavelength 7500 Ã… and the separation between the slits is doubled then the fringe width becomes

In Young's doble-slit experiment, if the monochromatic source of light is replaced by white light, then one sees

In a Young's double slit experiment an electron beam is used to obtain interference pattern. If the speed of electron decreases then

In young's double slit experiment, fringe order is represented by m, then fringe width is

In the Young's double slit experiment, the interference pattern is found to have as intensity ratio between the bright and dark fringes as 9. This implies that

In the Young's double slit experiment, the interference pattern is found to have as intensity ratio between the bright and dark fringes as 9. This implies that

A Young's double slit experiment uses a monochromatic source. The shape of the interference fringes formed on a screen is

Young's double slit experiment is performed with monochromatic light. A thin film is introduced in front of one of the slits

What is the effect on the interference fringes in a Young.s double-slit experimental due to each of the following operations : The monochromatic source is replaced by a source of white light?
