Why should I worry about UV rays?

This is the first in a series of three brief articles about the danger of UV rays with artwork.

What are UV Rays?

Before you say, "Omigod, I don't want to read about science," don't worry because this will be quicker than putting on sunscreen to block those pesky UV rays. The above chart of the electromagnetic spectrum(remember high school science?) shows that UV rays are to the left of visible violet light, hence the name ultraviolet, and are in the direction of increasing energy. That's why UV rays are dangerous for sunburn and for fading of artwork even though they are only 3% of the sun's rays that reach the Earth.
