I have a question that asks me to plot Plancks forumla for the wavelength dpendence of the intensity of black body radiation, and to use it to obtain an estimate for the temperature at which an object glows red hot.
Now I know Planck's formula (or its written in front of me), but I don't know what band of wavelengths I should plot. The EM spectrum? Other random wavelengths?
And for the red hot bit, is that the point at which the peak of the plot goes over a certain wavelength? The infra red end of the spectra?
Any help would be appreciated.
