Wave interference? Are you kidding? Popeye would have absolutely no chance of understanding anything unless it was considerably dumbed down. The analogy was for him, not anyone else. Even then, he couldn't understand the analogy. He is the one who turned baseballs into huge dodge balls even though I tried twice to steer him away from collisions. JC, Billybob, and SSDD are all whacko in their understanding of science.You were doing a-okay in the radiative transfer discussion we had. There was no need to degrade that interesting subject to the level where photons are becoming balls.You still don't understand the analogy.It seems you don't. All of those balls are thrown at the same time. If you really think none will hit in between never watched dodgeball. Let me take a pause and have you explain how they don't hit!
The balls are like photons. Thermal photons simply do not hit each other.
I thought I made it as simple as possible. I'm sorry you don't understand it as an analogy.
If light rays were colliding particle beams then it`s alright to use such an analogy.
It would have been better if you would have used the well explored subject of wave interference instead of balls hitting either a target or each other.
But getting back to your comment on wave interference. Black body radiation must be considered in terms of photons. That was how photons were hypothesized in the first place. Look up "ultraviolet catastrophe" and note Planck's solution.
If they really want to talk about EM waves they can only talk about superposition (uninteresting) not destructive interference since BB radiation is incoherent. Incoherent waves cannot cancel. Also those guys sometimes talk in terms of radio antennas canceling waves. Antennas can only redirect the coherent EM energy they can't destroy it because of the law of conservation of energy.
Antennas can only redirect the coherent EM energy they can't destroy it because of the law of conservation of energy.
A shorter wave can and does cause reflection of a longer wave. In other words, a warm object can reflect all radiation from a cooler one. Second law wins. And it is wholly consistent with COE. Its is also why the atmosphere has no hot spot.
Please tell me again how a less energetic wave can overpower a high energetic wave? You could win a Nobel for a perpetual motion machine.
