that doesn't make sense - if that would be the case, the back-emitted photon would have a random vector, not pertaining the same one as original one (thus preserving the picture beyond the sheet of metal).
you are stating somehow the direction of photon is preserved when absorbed by electron - absurd idea even for layman physics (not claiming I know how this works, but this can't be the way)
- archgoon 9y ago> you are stating somehow the direction of photon is preserved when absorbed by electron Well, that is how lasers work :) https://en.wikipedia.org/wiki/Stimulated_emission https://en.wikipedia.org/wiki/Stimulated_emission
- didgeoridoo 9y agoI barely understand even layman-level physics, but it would seem to me that this “absurd” idea is just a natural implication of the conservation of momentum? edit: to all the downvoters of saiya-jin — let the one who has never defended their incorrect intuitions in physics cast the first downvote!
- jacquesm 9y ago> let the one who has never defended their incorrect intuitions in physics cast the first downvote! Amen. This stuff is wildly counter-intuitive, we only properly know how mirrors work since we understand the photo electric effect, and even with that understanding it is still quite tricky because it requires insight into how stuff works at a level where direct observation is no longer possible without access to enormous resources.
- mcguire 9y agoI've had that same question before.
- dmd 9y agoThis is in fact how it works - otherwise mirrors wouldn't work!
