1. The problem statement, all variables and given/known data Calculate the density of states if the radiation oscillators are confined to a square (i.e. in two dimensions). 2. Relevant equations 3. The attempt at a solution This was one of the questions for my Modern Physics class, (we recently covered blackbody radiation), although based on the research I have been doing in hopes of understanding it, I think it has to do with Quantum Statistics. I have no idea what to do here, or how to start as I have not taken a quantum course. Of the stuff I've looked over in my modern textbook and online, I see that density of states can be found by taking the derivative of an equation representing the number of states in an area/volume with respect to energy. However, I have no idea how to find an equation for the number of states in a volume/area in the first place. Could anyone guide me on what to do for this problem? Thanks in advance!
