7. (0/4 Points) DETAILS PREVIOUS ANSWERS SERCP10 27.P.002. 1/4 Submissions Used MY NOTES ASK YOUR TEACHER Lightning produces a maximum air temperature on the order of 9.5 x 10 K, whereas a nuclear explosion produces a temperature on the order of 9.4 x 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 expect each to radiate most strongly. (a) lightning Amax = 3.05e7 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully nm It radiates most strongly in the radio wave X part of the spectrum (b) nuclear explosion *max 3.028 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully pm It radiates most strongly in the microwave X part of the spectrum
