It can be shown that the maximum in the wavelength distribution for blackbody radiation can be approximated well by the formula hc AmaxT= 4.965 kB where h = 6.62607015 x 10-34 J.sec, kg = 1.38068 x 10-23 J/K, and c 2.99792458 x 108 m/sec, T is in K, and Amax is given in m. (b) If the visible portion of the electromagnetic spectrum spans the wavelengths from 400 to 700 nm, what is the smallest temperature that would have its value of Amax in the visible range? Report your answer in K.

QUESTION 11 It can be shown that the maximum in the wavelength distribution for blackbody radiation can be approximated well by the formula hc AmaxT= 4.965 kg where h = 6.62607015 × 10-34 J.sec, kB = 1.38068 × 10-23 J/K, and c = 2.99792458 × 108 m/sec, Tis in K, and Amax is given in m. (a) If you have a normal body temperature of 40°C, what is the value of Amax in the radiation that you emit? Report your answer in nm, and be careful of the units for temperature.
