It's the other way around, UVA is the longest wavelength/lowest photon energy, while C has the shorter wavelength and the most energy. The shorter the wavelength the more powerfull.

Its not because i have seen otherwise, and suntan lotion protects against a/b and doesnt bother against c. Uva is produced by sunbeds and is considered the most harmful.

The earths ozone entirely blocks C that's why. This is gcse physics here.

I have to cover myself with the stuff, spf50 usually, then again i am of the ginger persuasion. If sensitive skin is the only downside to my genetic superiority then it's a price worth paying.
