As light is a wave, it travels in an oscillating pattern:
| _ _ _ _ _ _ _ _ |/_\ _ /_\___/_\ _ /_\___/_\ _ /_\___/_\ _ /_\___ | \_/ \_/ \_/ \_/ \_/ \_/ \_/ \_/
In my understanding, if you decrease the amplitude, the oscillation will tend to straighten out. What if you manage to straighten it out completely, i.e. make photons move completely straight (see below)?
Is this possible?
What will its properties be?
Note: My theory on how to do this (impractical/impossible)-- You first cool down the photon to 0K. This will cease all oscillations, then somehow apply a force. Does this make any sense? Are there any better theories?
