About too much light in a room

  1. Jul 8, 2006 #1
    Cover all the walls of the room where you are now of a super reflecting membrane.
    The glass of the lamp must be the glass that police uses for the interrogatories, in order that light just can exit.

    The photons that comes out from the lamp (powerful one) must acccumulate in the room, then after some time, i don't know how much, what happends?
    There will be always space for other photons?

    Photons are bosons. There's nothing to prevent them from occupying the same "state", including phase space, as many as they want.

    Furthermore, there are no "mirrors" that are 100% reflecting. Try increasing the brightness of a light hitting a mirror. Eventually, it will become warm, meaning it is absorbing some of the light hitting it. The conduction electrons that are reponsible for the "reflection" process in an ordinary mirror (a mirror is nothing more than a thin metal film) generate heat as it oscillates at the metal's surface due to the light's electric field.

    i thought that the indetermination principe or something like it does not let 10 things to stay in the same poin of space

    What you're thinking of is the Pauli Exclusion Principle, and it applies to same-spin fermions, not bosons. Fermions resist being forced into the same quantum state with similar particles with the same spin.

    That's an incorrect interpretation of the Heisenberg Uncertainty Principle.
