## Question:

Suppose you want to conduct the double-slit experiment with an electron that has kinetic energy equal to 100 eV. You design the experiment so that the slits are d = 100 m apart. What is the position on the screen of the third (n = 3) bright spot in the electron's interference pattern?

## Interference due to Electrons:

Because electrons have some kinetic energy, they have some wavelength and can interfere in Young's Double Slit Experiment. The position of the fringe deviates more from the central fringe as the order of the fringe increases.
