Young’s Double Slit






The spacing and position of the slits can be adjusted.

Young’s Double Slit experiment is a phenomenon in which light passing through two slits creates a specific pattern.
Each slit acts as a source of coherent waves which spread out forming an interference pattern that can be seen on a screen.

Why does the pattern have bright (or dark) parts?
How do you narrow (or broaden) the spacing of patterns?
