Question

Consider the problem of the distribution of blackbody radiation described in Figure 40.1. Note that as T in- creases, the wavelength Amax at which I(?, T) reaches a maximum shifts toward shorter wavelengths. (a) Show that there is a general relationship between tempera- ture and ?max (known as Wien's displacement law which states that Txconstant. (b) Obtain a nu- merical value for this constant. [Hint: Start with Planck's radiation law and note that the slope of1(2, T) versus ? is zero when ? hoax.]
