I was watching this Feynman’s talk where he said to the reporter that “I can see you because you’re in front of me, and person on my left can see person straight to him, on my right”,because light waves are always reflecting and bouncing off, it’s our perception.
That got me to question this about light and then all electromagnetic waves in general.
Apologies if this is a stupid question, just curious.
In: Physics
A photon is a particle, the flow of photons is a wave.
When two waves intersect, they do not collide, they simply add or subtract from each other for the brief time that they cross.
It took a long time for the great minds to come to this conclusion, see https://global.canon/en/technology/s_labo/light/001/11.html for the history.
