My physics textbook is talking about blackbodies and has a graph showing Power radiated as a function or wavelength on the y axis and wavelength on the x axis. The slope grows to it's maximum value exponentially and then decays exponentially. They clarify that the peak of the graph is the wavelength that provides the maximum power radiated, and go on to talk about Wien's law. My question is why is the most power not radiated at the shortest wavelength? E = hc/λ? Why is it dependent on the temperature?
