How does a single photon show a phase shift? Using the interference pattern created by light traveling through a double slit, the resource asks whether the interference pattern would still show if only one photon of light is sent at a time. The video sets up an experiment to find out and displays the resulting data as part of the Veritasium playlist.
- Research the history of scientists' theories about light
- If the class is not familiar with the double slit experiment, you can find it here
- The class should have some concept of light and its properties
- Contains a graphical display of the waves being out of phase
- Provides an explanation of why the light in a double slit experiment using the sun appears as a blob
