word sets- But photons are extremely odd particles indeed.
- But here things are very different: each individual photon behaves like a wave entirely on its own!
- Consider a photon which is polarised parallel to the optical axis of P,.
- Consider also, this kind of phenomenon affects not just photons, but every particle in every interaction.
- How can it be that by allowing the photon an alternative route, we have actually stopped it from traversing either route?
- How will you capture photons fast enough to propel the sail at speed and over long distances?
- The great advantage of using lower-energy photons rather than X-rays is the greater resolution attainable.
- The two photons are like the left and the right eyes of the cat.
