In Young's Double slit Experiment, if one of the slits is closed, what happens?

In a Young's double slit experiment the separation between the slits is 0.10 mm, the wavelength of light used is 600 nm and the interference pattern is observed on a screen 1.0 m away. Find the separation between the successive bright fringes.

A Young's double slit experiment is performed with white light.

In Young's double slit experiment light waves are coherent. Why?

In a Young's double slit experiment, the separation between the slits = 2.0 mm, the wavelength of the light = 600 nm and the distance of the screen from the slits = 2.0 m. If the intensity at the centre of the central maximum is 0.20 W m^-2 , what will be the intensity at a point 0.5 cm away from this centre along the width of the fringes ?

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 separatation of the slit is 2mm. The screen is at a distance 1m from the slit. How many bands can be seen in a space of 1cm? Given wavelength of light =400nm.

A beam of light consisting of two wavelengths, 6500 Å and 5200 Å is used to obtain interference fringes in a Young's double slit experiment (1 Å = 10^(-10) m). The distance between the slits is 2.0 mm and the distance between the plane of the slits and the screen in 120 cm. (a) Find the distance of the third bright fringes on the screen from the central maximum for the wavelength 6500 Å (b) What is the least distance from the central maximum where the bright fringes due to both the wavelengths coincide ?
