Best Answer: Good question. On average clouds reflect 60% of incoming solar radiation which includes short wave UV. The thicker the cloud the greater the reflection, from 60 - 90%. For thin clouds the albedo, or relection is 30 - 50%, which explains why we can still receive UV on cloudy days.

UVA rays have the longest wavelengths, followed by UVB, and UVC rays which have the shortest wavelengths. While UVA and UVB rays are transmitted through the atmosphere, all UVC and some UVB rays are absorbed by the Earthâs ozone layer. So, most of the UV rays you come in contact with are UVA with a small amount of UVB. Like all forms of light on the EM spectrum, UV radiation is classified by wavelength.
