Trying to explain phenomena using photons rather than waves can, at times, be extremely lumpy!I can never understand why people are so in love with photons and want to use them to explain everything , at all costs.
Anyone would think that em waves were REALLY photons.They certainly have their place - but only when it's appropriate.I don't know of many lens designers who use particles to explain and design their optical systems.
physicsforums.com/archive/index.php/t-32102.htmlIf you read this, or at least some of it, you may be enlightened or you may be confused; particularly if you have always regarded photons as little bullets.It certainly comes to no real conclusions - but can you?There are a lot of mis conceptions about the little devils (or are they little?).It seems clear that the only 'packet-like' thing about them is the amount of energy each one is associated with. The old 'corpuscular' theory of light is responsible for a lot of the problems we seem to have in visualising what is going on. Heisenberg spoils most of the pictures of them which we carry in our minds.How big are they?
How long do they last?
How is the energy carried?
