In a double slit experiment, the separation between the slits is d and distance of the screen from slits is D. If the wavelength of light used is lambda and I is theintensity of central bright fringe, then intensity at distance from central maximum is

In a double slit experiment the separation between the slits is d and distance of screen from slits is D. If the wavelenth of light used is lamda and I is the intensity of central bright fringe, then intensity at distance x from central maximum is given by

In Young's double - slit experiment, the distance between slits is d = 0.25 cm and the distance of the screen D = 120 cm from the slits. If the wavelength of light used is lambda=6000Å and I_(0) is the intensity of central maximum, then the minimum distance of the point from the centre, where the intensity is (I_(0))/(2) is kxx10^(-5)m . What is the value of k?

In a Young's double slit experiment, the separation between the slits is 2xx10^(-3) m and the distance of screen from the plane of slits of 2m. Light of wavelengths in the range 3500Å to 7000Å is allowed to fall on the slits. The wavelength that will have a maxima on the screen at 10^(-3) m from the central maxima is
