# Photon wavelength probability distribution for blackbody

Hey everyone,

This is my first time posting on PF!

I want to model the photons ejected from a blackbody source at temperature T.
The question I want answered is: given a photon is detected, what is the probability of the photon having a wavelength λ? This amounts to just attaining the probability density function for the different wavelengths.

We normally talk about blackbodies in terms of intensity, or more specifically spectral radiance, but I want to talk about the individual photon wavelength distribution.

My current thoughts are:
Any thoughts on whether this is right?

Peter.
