Two identical coherent sources produce a zero order bright fringe on a screen. If `beta` is the band width, the minimum distance between two points on either side of the bright where the intensity is half that of maximum intensity is half of maximum intensity is

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 Young's double slit experiment with light of wavelength lamda the separation of slits is d and distance of screen is D such that D gt gt d gt gt lamda . If the fringe width is bea , the distance from point of maximum intensity to the point where intensity falls to half of maximum intensity on either side is

In a Young's double slit experiment with light of wavelength lamda the separation of slits is d and distance of screen is D such that D gt gt d gt gt lamda . If the fringe width is bea , the distance from point of maximum intensity to the point where intensity falls to half of maximum intensity on either side is

If the fringe width is bea , the distance from point of maximum intensity to the point where intensity falls to half of maximum intensity on either side is

The ratio of the intensity at the centre of a bright fringe to the intensity at a point one-quarter of the distance between two fringe from the centre is

Two coherent sources produce waves of different intensities which interfere. A fter interference, the ratio of the maximum intensity to the minimum intensity is 16. The intensity of the waves are in the ratio :
