Assertion : A white source of light during interference forms only white and black fringes.
Reason : Width of fringe is inversely proportional to the wavelength of the light used.

Assertion : When a thin transparent sheet is placed in front of both the slits of Young's experiment, the fringe width will remains same. Reason : In Young's experiment, the fringe width is directly proportional to wavelength of the source used.

Study the interference fringes with white light.

When white light source is used for obtaining interference, the central fringe is ………………. .

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.

In interference with two coherent beams of light , the fringe width is
