- Electrons go through a single slit 150 nm wide and strike a screen 24.0 cm away. You find that at angles of +/- 20.0 degrees from the center of the diffraction pattern, no electrons hit the screen but electrons hit at all points closer to the center.

The x-rays scatter from the electrons within the sample, imparting momentum to the electrons, which are initially at rest in the lab frame.

Suppose a laser beam is placed behind the screen in an attempt to determine which slit the electron passes through. In this scenario, each single electron will pass through and cause to appear on the detector screen.
