Lightning produces a maximum air temperature on the order of 104K, whereas a nuclear explosion produces a temperature on the order of 107K. Find the order of magnitude of the wavelength radiated with greatest intensity by each of these sources. Name the part of the EM spectrum where you would expect to radiate most strongly.

tex]2.898\times 10^{-7}\ \text{m}[/tex] ultraviolet region

x-ray region

Explanation:

T = Temperature

b = Constant of proportionality =

= Wavelength

From Wein's law we have

The wavelength of the radiation will be and it is in the ultraviolet region.

The wavelength of the radiation will be and it is in the x-ray region.
