The width of fringes ...... as the Young's double slit experiment moves from air to water

becomes infinite

decreases

increacses

does not change

Text Solution

Verified by Experts

The correct Answer is:

Width of slit `(2barX) prop lambda`, experiment done from air to water, wavelength of light decreases hence width of fringes also decreases.

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.
