When it comes to electromagnetic energy, he shorter the wavelength, the higher the frequency.

Thus, we can arrange UV light as follows:

Shortest wavelength = UVC = highest frequency

Medium wavelength = UVB = medium frequency

Longest wavelength = UVA = lowest frequency

The waves with the shortest wavelength/highest frequency have the

most energy, and thus UVC waves are the most damaging and the

most penetrating.

As far as which is most abundant at ground level, we have

UVA making up the majority, at >98%

UVB next at < 3%

UVC last at <1%

The abundance at ground level is a consequence of the fact that the

Earth's atmosphere blocks just everything shorter than 200 nm. Thus,

most of what gets through is the longer wavelength UVA (315-400nm),

and a small portion of UVB (280-315nm). Much of the UVC (100-280nm) gets blocked.

RE:

arrange UVA, UVB and UVC in order of...?

1) Wavelength

2)Frequency

3)damage capability

4) relative abundance at ground level

I&#39;m pretty sure wavelength in order is: uva, uvb then uvc. Damage is: uvc, uvb and uva, but i&#39;m not sure about the other two.

Uvc Wavelength
