In Young's double slit experiment if d, D and lamda represent the distance between the slits, the distance of the screen from the slits and wavelenfth of light used respectively, then the band width is width is inversely proportional to

What is the effect on the interference fringes in a Young' double slit experiment due to each of the following operations. a. the screen is moved away from the plane of the slits. b. the (monolchromatic) source is replaced by another (monochromatic) source of shorter wavelength. c. the separation between the two slits is increased. d. the source slit is moved closer to the double slit plane: e. the width of the source slit is increased. f. The monochromatic source is replaced by a source of white light? (in each operation, take all parameters, other than the one specified, to remain unchanged).

Chromosomes complete their condensation and become clearly visible along with their sister chromatids during _______.

The diffraction pattern becomes invisible when the slit is very wide. Give reason.

In Young 's double slit experiment the distance between the slits and the screen is doubled the separation between the slits is reduced to half. As a result the fringe width.

In Young's double slit experiment, the distance of the screen from the two slits in 1m. When a light of wavelength 600nm is allowed to fall on the slits width of the fringes obtained on the screen is 2mm. Calculate the width of the fringe if the wavelength of the incident light is 400nm. Calculate band width in each case if the arrangement is immersed in water of refractive index 1.33.

The line-width of a bright fringe is sometimes defined as the separation between the points on the two sides of the central line where the intensity falls to half the maximum. Find the line-width of a bright fringe in a Young's double slit experiment in terms of lamda , d and D where the symbols have their usual meanings

In a single-slit diffraction experiment, the width of the slit is made double the original width. How does this affect the size and intensity of the central diffraction band?
