Hey guys, just trying to get my head around this one..
Why do UV rays effect polymer chains so much? I understand that they weaken the bonds within the chains to create free radicals which then go on to react with other things which eventually makes the whole chain degrade as a whole, but why are UV rays in particular so harmful?
Don't they have less energy/photon than visible light, which would make polymers mores susceptible to degration from visible light? Or is it something like there's more UV light rays than visible light rays?
I'm confused!
Thanks!
Also, I wasn't sure to put this in the physics section or here so feel free to move it if I've made a boo boo. :)
