In an arrangement to view the interference pattern produced by a wedge of liquid between a microscope slide and a glass block thhe interference pattern obtained is made is equal spaced parallel fringes. The fringe separation (or fringe width) can not be decreased by which of the following actions.

(a) If one of two identical slits producing interference in Young's experiment is covered with glass so that the light intensity passing through it is reduced to 50%, find the ratio of the maximu and minimum intensity of the fringe in the interference pattern. (b) What kind of fringes do you expect to observe if white light is used instead of monochromatic light ?

An interference pattern was made by using red light. If the red light changes with blue light, the fringes will become

Statement I: In interference, all the fringes are of same, width Statement II: In interference, fringe width is independent of the position of fringe.

Laser light of wavelength 630 nm incident on a pair of slits produces an interference pattern in which the bright fringes are separated by 8.1 mm. A second laser light produces an interference pattern in which the fringes are separated by 7.2 mm. Calculate the wavelength of the second light.

Laser light of wave length 600 nm incident on a pair of slits produces an interference pattern in which the bright fringes are separated by 8mm. A second light produces an interference pattern in which the fringes are separated by 12 mm. Calculate the wavelength of the second light.

Laser light of wavelength 630 mm incident on a pair of slits produces as interference pattern in which the bright fringes are separated by 8.1 mm. A second light produces an interference pattern in which the fringes are separated by 7.2 mm. Calculate the wavelength of the second light.
