Derive an expression for fringe width in Young's double slit interference of light.

State two conditions for two light sources to be coherent. Derive an expression for the fringe width in Young.s double slit experiment for interfernce with suitable diagram.

What happens to fringe width in the Young's double slit experiment,if its is performed in glycerine insteaad of air?

The fringe width in a Young.s double slit interference pattern is 2.4 xx 10^(-4) m, when red light of wavelength 6400 overset@A is used. By how much will it change,if blue light of wavelength 4000 overset@A is used?

How will the angular separation and visibility of fringes in Young's double slit experiment change when Width of the source-slit is increased.

A monochromatic beam of light is used for the formation of fringes on the screen by illuminating the two slits in the Young's double slit interference experiment. When a thin film of mica is interposed in the path of one of the interfering beams, then
