For a blackbody, the frequency at which maximum energy is emitted is 3 x 1013 Hz: A. Give a wavenumber for the wavelength of the infrared emission? B. What is the temperature of the blackbody? C. What is the total radiance emittance for the blackbody? D. Consider an emitter (with an emissivity of 0.5) at the same temperature of the blackbody (obtained from B). What is the total power lost by this emitter if its area is 2 m2 ?
