I'm not in favor of the term 'conductor', which implies electron flow, in
this discussion, as the electron is a phenomenon not directly responsible
for the principles of refraction/reflection of light...

Actually, metals do respond to light in several ways.. One is the
photoelectric effect there's your electron flow... And, thin layers of
metals are coated onto glass surfaces to alter it's refraction/reflection
characteristics to light, so metal can both refract and reflect at light
frequencies, depending upon the bulk state, without depending upon electron
flow...

And glass is too nonspecific a term, as various elements/molecules can be
incorporated into basic soda glass to alter it's transparency to EM energy
at various wavelengths ranging from rf to light and beyond...

The point you make about all material/physical response depending on
wavelength is right on... The only difference between the radio signal from
the local rock station and a gamma ray, is wave length...

Enough QED physics here - I'm off the topic...

Metal is not a conductor of light.
Glass is not a conductor of RF.


Nothing fundamental here. Glass is not a conductor of UV either. And
distinguish RF radiation (wide light) from RF electric signals (electrons
vibrating quickly, but not as fast as they would need to to transmit LF)

Wavelength dependence. It's what's for dinner.
