How does the angular separation of interference fringes change in Young's experiment, if the distance between slits is increased .

A beam of light consisting of two wavelengths, 650 nm and 520 nm is used to obtain interference fringes in a Young's double-slit experiment. If distance between slit and screen is 1.2 m and distance between two-slits is 2 mm. Find the distance of the third bright fringe on the screen from the central maximum for wavelength 650 nm.

A beam of light consisting of two wavelengths, 650 nm arid 520 nm is used to obtain interference fringes in a Young's double-slit experiment. If distance between slit and screen is 1.2 m and distance between two-slitsis 3 mm. What is the least distance from the central maximum where the bright fringes due to both the wavelengths coincide?

Two straight and narrow parallel slits separated by 3mm are illuminated by a monochromatic light of wavelength 5460 overset (@)(A) . Interference fringes are obtained at a distance of 60 cm from the slits. Find the change in fringe width if the distance between the slits is i) increased by 1 mm and ii) decreased by 1mm.

Plane wavefront of light of wavelenght 5500 overset (@)(A) is incident on two slits in a screen perpendicular to the direction of light rays. If the total separation of 10 bright fringes on a screen 2 m away is 2 cm, find the distance between the sits .

In Young's double slit experiment using monochromatic light, the fringe pattern shifts by certain distance on the screen when mica sheet of refractive index 1.6 and thickness 1.964 microns is introduced in the path of one of the interfering waves. The mica sheet is then removed and the distance between the slits and screen is doubled. It is found that the distance between successive maxima now is same as the observed fringe shift upon the introduction of the mica sheet. Calculate the wavelength of the monochromatic light used in the experiment.

Distinguish between Young's experiment and Bi prism experiment

Explain Young's Double Slit Experiment.

In a biprism experiment , the band width is found to be increased by 25% of the initial . If the distance between slit and eyepiece is increased by 20 cm then the initial distance between slit and eyepiece is
