Homework Statement
A cavity contains black body radiation at temperature at T=500K. Consider a optical mode in the cavity with frequency w=2.5x10^(13) Hz. Calculate;
(a)the probability of finding 0 photons in the mode.
(b)the probability of finding 1 photon in the mode
(c)the mean number of photons in the mode.
Homework Equations
The Attempt at a Solution
Okay so I'm not sure where to start basically with part (a) and (b), but I made an attempt at part (c)
I used the equation;
[tex]\bar{n}=\frac{1}{e^{\frac{\hbar\omega}{k_b T}}-1}=2.51\times 10^{-17} Photons[/tex]
would really love a nudge in the right way, I've just gone blank on probability it's been so long since I last did it.
