The total power per unit area radiated by a black body at a temperature Tis the area under the I(A,T')-versus-A curve as shown in Figure S9.3. (a) Show that this power per unit area is | 1(1,T) da = oT* where I(A,T') is given by Planck's radiation law and o is a constant independent of T. This result is known as Stefan's law. (See Section 19.6.) To carry out the integration, you should make the change of variable x= hc/Ak,Tand use " x* dx _ m* 15 (b) Show that the Stefan-Boltzmann constant o has the value = 5.67 x 10-8 W/m? - K 15c

For the thermal radiation from an ideal blackbody radiator with a surface temperature of 2000 K, let Ic represent the intensity per unit wavelength according to the classical expression for the spectral radiancy and IP represent the corresponding intensity per unit wavelength according to the Planck expression.What is the ratio Ic/IP for a wavelength of (a) 400 nm (at the blue end of the visible spectrum) and (b) 200 mm (in the far infrared)? (c) Does the classical expression agree with the Planck expression in the shorter wavelength range or the longer wavelength range?

A blackbody is an object with a radiation spectrum that is dependent solely on its tempera- ture. A blackbody spectrum (or spectral radiancy curve) is described by the Planck Radiation Law. (a) i. Sketch the spectral radiancy curves for blackbodies with temperatures of T = 4000 K and T = 6000 K, respectively. Describe the main differences between the two curves in terms of the appropriate physical laws defined as a function of tempera- ture. ii. What is the wavelength at peak intensity for each blackbody? State the part of the electromagnetic spectrum to which each wavelength belongs. (b) Use the Planck Radiation Law to determine the power radiated per unit area between the wavelengths A 500 nanometres and λ = 503 nanometres for the T 6000 K blackbody. What fraction of the blackbody's radiancy lies in this wavelength range? =
