The Double Slit Experiment<br />
• At the screen, constructive interference between the plane waves from<br />
each slit yields a regular array <strong>of</strong> bright lines, corresponding to a high<br />
intensity <strong>of</strong> electrons. In between each pair <strong>of</strong> bright lines, is a dark band<br />
where the plane waves interfere destructively, i.e. the waves are out <strong>of</strong><br />
phase with one another.<br />
• The spacing between the bright lines at the viewing screen is<br />
• It is notable that the fringe pattern is independent <strong>of</strong> intensity. Thus, the<br />
interference effect should be observed even if just a single electron is<br />
fired at the slits at a time.<br />
• The only conclusion is that the electron – which we are used to thinking<br />
<strong>of</strong> as a particle - also has wave properties.
