What will be the effect on fringe width if distance between the coherent sources is made half in Young's double slit experiment.

Prove that the fringe width of both the brigth and dark fringes in interference is same in Young's double slit experiment.

Give two differences between fringes formed in single slit diffraction and Young's double slit experiment.

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 are coherent sources of light? Draw the variation of intensity with position, in the interference pattern of Young's double slit experiment.

In these question, a statement of asertion followed by a statement of reason is given .Choose the correct answer out of the following choices: Assertion and reason both are correct statements and reason is correct explanation for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement but reason is correct statement. Assertion:In Young's double slit experiment,the fringe width for dark fringes is equal to that for white fringes . Reason:In Young's double slit experiment performed with a source of white light ,only black and white fringes are observed.

A beam of light consisting of two wavelegnths, 6,500 overset @A and 5,200 overset @A is used to obtain interference fringes in a Young's double slit experiment. The distance between the slits is 2 mm and the screen is 120 cm. What is the least distance from the central maximum, when the bright fringes due to both the wavelengths coincide?
