geoff hellman  asked the Naked Scientists:

Hi Chris,
I have heard that moonlight damages material, (ie; makes it fade),  such as curtains and other furnishing fabrics more than sunlight. Is this true, and if so how, as moonlight is only reflected sunlight?

Cheers,
Geoff
What do you think?

I don't think it's true. Not only is moonlight much weaker but the moon won't reflect the hard UV very well so the most damaging bit of the sunlight is removed whne it's reflected from the moon.

This is a really bizarre notion! How much energy could possibly be getting here from the moon? Even if it were a perfect reflector to UV, the illumination would be reduced by a similar amount to the reduction in visible light level.

Moonlight is a combination of reflected sunlight and reflected starlight, with sunlight being by far the greatest component, so there is nothing in moonlight that is not present in sunlight, or to a much lesser degree, starlight.

Well, unless there happens to be a large area on the moon, as yet undiscovered, that is able to change the frequencies present in the incident light that is eventually reflected back to us.

Moonlight DOES indeed have an effect on material.....like the Hulk, I turn into a wolf-sheep and split my garters !!

Maybe its a rumour started by people hoping to get a look-see at people undressing at night, since they might have rolled their curtains up to save them from the terrible moonlight
