I'm not really sure what you mean, but it could be heated air because 'rises' could mean temperature rising, and when temperature rises, the air heats up... i hope I'm correct and this helps you. correct me if I'm wrong.
The ranges of frequency are:
UVA: ![[7.50-9.38]\cdot 10^{14} Hz](https://tex.z-dn.net/?f=%5B7.50-9.38%5D%5Ccdot%2010%5E%7B14%7D%20Hz)
UVB: ![[9.38-10.71]\cdot 10^{14} Hz](https://tex.z-dn.net/?f=%5B9.38-10.71%5D%5Ccdot%2010%5E%7B14%7D%20Hz)
Explanation:
The relationship between frequency and wavelength for an electromagnetic wave is the following:

where
f is the frequency
is the speed of light
is the wavelength
For the UVA, the range of wavelength is 320 nm - 400 nm, so

So the corresponding frequencies are

For the UVB, the range of wavelength is 280 nm - 320 nm, so

So the corresponding frequencies are

So the ranges of frequency are:
UVA: ![[7.50-9.38]\cdot 10^{14} Hz](https://tex.z-dn.net/?f=%5B7.50-9.38%5D%5Ccdot%2010%5E%7B14%7D%20Hz)
UVB: ![[9.38-10.71]\cdot 10^{14} Hz](https://tex.z-dn.net/?f=%5B9.38-10.71%5D%5Ccdot%2010%5E%7B14%7D%20Hz)
