Lightning produces a maximum air temperature on the order of 8.9 ✕ 103 K, whereas a nuclear explosion produces a temperature on the order of 9.4 ✕ 106 K. Use Wien's displacement law to calculate the wavelength of the thermally-produced photons radiated with greatest intensity by each of these sources. Select the part of the electromagnetic spectrum where you would...
