- What gives you that idea? The wavelength is just the distance from peak to
- peak (or trough to trough) of the electric (or magnetic) portion of the wave.
- I've never heard that photons were exactly "one wavelength long". More
- likely, all photons are something like a meter long (or a millimeter or
- a kilometer), and photons with a shorter wavelength just have more "wiggles"
- crammed into that one standard photon length.

- two light beams have to be before they'll interfere with each other?)
