In Young's double slit experiment, using monochromatic

Last updated: 7/8/2022

In Young's double slit experiment, using monochromatic light, fringes are obtained on a screen placed at some distance from the slits. If the screen is moved by 5 x 10-²m towards the slits, the change in the fringe width is 3 x 10-5m. If the distance between the two slits is 10-³m, calculate wavelength of the light used.
