High frequency amazes me

Electricity and Magnetism Level 2

Can a cylindrical hollow conductor conduct high frequency signals through it?

Yes, the charge carriers can travel at the surface of the conductor, making it possible to conduct. No, if the conductor is not hollow it will definitely conduct. Yes, as hollow conductors behave as waveguide at high frequency. No, it cannot conduct.
