Do mirrors Reflect UV rays?

UV rays can be reflected by water, pavement, or sand (which is why you can get burned under an umbrella on the beach) so I would think a mirror would reflect UV very well.
 
Since UV rays are very close (in wavelength and energy) to the visible spectrum, I would expect that a conventional mirror would also be able to reflect UV.
 
Yes UV rays can be reflected by mirrors, and can even be focused by certain mirrors...I believe it is convex mirrors...But I'm not sure about that part.
 
NO*

*Glass (and many plastics) stops low wavelengths of light, that's why you don't get a tan behind windows. If the mirror is made of glass, it won't reflect the all the UV light.

This is a problem with making ICs, since the low wavelength lasers needed for modern ICs can't be reflected with a plain glass mirror.

then why does my right arm get sunburned when driving with the window up?

Normal windows and mirrors block most of the UV light, but not all. The remaining is enough to cause tanning.

Perhaps I'm misreading you, but UV is a higher frequency band than visible light... IR is what's lower.

Sorry, I was drunk ;)
I meant wavelength. UV is high frequency/short wavelength.
