Define coherent sources of light, fringe width and interference of light. Show that the width of dark fringe is equal to the width of bright fringe in Young's double slit experiment.

What is the effect of slit width and wavelength of light source on fringe width of the fringes formed by 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.

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.
