Answer to Question #152118 in Optics for Mana

Question

In Young's double slit experiment,a light of wavelength Is exposed to the slits which are separated by a distance d.analyze what change in the fringes will take place on the screen.will there any change be observed on the screen if one slit is closed?

Answer 1

Answer

In Young's double slit experiment,a light of wavelength Is exposed to the slits which are separated by a distance d then fringe is given

$\beta=\frac{D}{d\lambda}$

This tells all changement.

If one of slit is closed then interference fringes are not formed on the screen but a fringe pattern is observed due to diffraction from slit.
