In a Young's double slit experiment, slits are seperated by a distance d and screen is at distance D, `(D gt gt d)` from slit plane. If light source of wavelength `lambda(lambda ltlt d)` is used. The minimum distance from central point on the screen where intensity is one fourth of the maximum is `(D lambda)/(nd)`. Find the value of n.

In Young's double slit experiment the slit separation is d = 1 mm and the screen is at a distance D = 1m. Monochromatic light of wavelength lambda = 5000A^@ is used. Then the distance of the third dark form the central bright fringe is

In Young's double slit experiment slit separation is d, and distance of screen from slate is D (D>>d). If first dark fringe is formed in front of one of the slit, then web length of light used will be

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

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 interference experiment the fringe pattern is observed on a screen placed at a distance D from the slits. The slits are separated by a distance d and are illuminated by monochromatic light of wavelength lamda . Find the distance from the central point where the intensity falls to (a) half the maximum, (b) one fourth of the maximum.
