Scenario A: We have 2 mirrors at a distance of 1 meter from each other. No photons. We wait until gravity pulls the mirrors together.
Scenario B: We have 2 mirrors at a distance of 1 meter from each other. Some photons bounce between the mirrors and the distance between the mirrors doesn't decrease due to gravity for a while and the photons lose their energy because of this. Then we wait until gravity pulls the mirrors together.
Where did the energy of the photons in Scenario 2 disappear?

You're not listening and I'm going to stop answering. >distance between the mirrors doesn't decrease
>the photons lose their energy For the Nth time, the photons DON'T lose any energy so long as the mirrors don't move!!!!!!
Matthew Richardson
I have no idea why photons only lose energy due to the movement of the mirrors but not due to working against gravity regardless of net movement. So let's change the scenarios slightly so that there is actual movement.
Scenario A: Mirrors apart 1 meter. No photons. Gravity pulls them together.
Scenario B: Mirrors apart 1 meter. Photons push them apart some more so we get 1.01 meter separation. Gravity pulls mirrors a bit closer together and they are at 0.99 meters. Photons push them back to 1.00 meters apart. Gravity pulls them together.
I fail to see the difference but now there's the movement you wanted. Still, we seem to have lost the photons.
Carter Phillips
One last time. Photons lose energy when they push them apart. Photons gain it all back when the mirrors move together again.

After some of the posts I've seen on Veeky Forums, very little shocks me. Some people just don't know. Others don't want to know.
There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge." ---------- Isaac Asimov He was very depressed in his last days.

>The photon may only interact with one atom but the entire mirror moves. Does your body moves if I throw at you a grain of sand? That impulse will probably wont even reach your back and be conserved as a tiny amount of heat.
Noah Richardson
You know zero physics. Momentum and heat aren't the same. Bother some other board.
