What happens if we close one slit in a Young's double slit experiment?

Text Solution

Verified by Experts

In the Young experiment closing one slit out of two slit then it will act like one slit.
Now have a hole or slit, the diffraction pattern will be formed on screen due to diffraction occurred by a slit.
The centre of the central bright fringe will appear at a point which lies on the straight line `SS_(1)` or `SS_(2)`.

Describe Young's double slit experiment.

Assertion:- When a width of one of the slits of Young's double slit experiment is double that of the other the brighter frings are nine times brighter then the dark fringes. Reason:- The amplitudes of the wave is proportional to the width of the slit.

White light is used to illuminate the two slits in a Young's double slit experiment. The separation between the slits is b and the screen is at a distance d (gt gtb) from the slits At a point on the screen directly in front of one of the slits, certain wavelengths are missing some of these missing wavelengths are

Let S_(1) and S_(2) be the two slits in Young's double-slit experiment. If central maxima is observed at P and angle /_ S_(1) P S_(2) = theta , then fringe width for the light of wavelength lambda will be (assume theta to be a small angle)

In figure, parallel beam of light is incident on the plane of the slits of a Young's double-slit experiment. Light incident on the slit S_(1) passes through a medium of variable refractive index mu = 1 + ax (where 'x' is the distance from the plane of slits as shown), up to distance 'I' before falling on S_(1) . Rest of the space is filled with air. If at 'O' a minima is formed. then the minimum value of the positive constant a (in terms of l and wavelength lambda in air) is

The maximum number of possible interference maxima for slit-separation equal to twice the wavelength in Young's double-slit experiment is

Statement-1: In Young's double slit experiment the two slits are at distance d apart. Interference pattern is observed on a screen at distance D from the slits. At a poit on the screen when it is directly opposite to one of the slits, a dard fringe is observed then the wavelength of wave is proportional of square of distance of two slits. Statement-2: In Young's double slit experiment, for identical slits, the intensity of a dark fringe is zero.
