Eli5: how come photon doesn’t have mass?
In: Physics
Think about a wave of water. The water has mass. The wave doesn’t.
Light isn’t stuff. Its a wave travelling through the stuff.

I’ve heard that light moves slower in different mediums. I also heard about an experiment that managed to “freeze” light.
If I slow down a photon so it’s not moving, then release it into a vacuum, where did its energy to get to light speed come from?
Same with electrons, why can they just keep moving?
