Do mirrors reflect only visible lights, or do they reflect light of other frequencies (if so then which types--x-ray, infrared, gamma, etc)?

Yes and no, a normal mirror reflects visible light and likely near IR and UV, but it's not optimized for anything past that. Mirrors can be made for most forms of light, though it gets far harder the smaller the wavelength gets, x ray mirrors have to be almost edge on to work well, much like how glass becomes more reflective when looked at from the side rather then straight on.
