Light with a wavelength of 590 nm passes through a slit 7. 00 µm wide and falls on a screen 1. 60 m away. Find the linear distance on the screen from the central bright fringe to the fourth dark fringe on either side.
The width of the central bright fringe in a diffraction pattern on a screen is identical when either electron or light (vacuum wavelength = 512 nm) pass through a single slit. The distance between the screen and the slit is the same in each case and is large compared to the slit width. How fast are the electrons moving?
