Electromagnetic waves are time varying electric and magnetic fields that are coupled to each other and that travel through empty space or through insulating materials. (Electromagnetic waves cannot travel through conducting materials although they can travel along their surfaces). Electromagnetic waves are transverse waves, i.e. the directions of their electric and magnetic fields are perpendicular to the direction in which the wave travels.

Because a conductor already carries current and it has a magnetic field around it. This magnetic field stops the electronic waves to travel through it.

They can. The magnetic waves are responsible
for electric generators to produce electricity, for electric motors to use electricity to run and also
transformers use magnetic waves to transfer one kind of electricity to another. I'm sure there are more uses. When magnetic waves go through a conductor (wire) an electrical current is produced in that conductor.

They can -- consider the coaxial cable that feeds your television set. But in terms of a mirror, the conductive surface shorts out the E-field of the wave, so there cannot be a solution of Maxwell's equations within a conductor other than one with decaying exponentials.

The electric field at the surface of the conductor must be zero (short circuit) so the wave's energy gets absorbed.

i imagine you're incorrect because it may commute and this the most of screening that's to guard tender digital contraptions by ability of surrounding it by ability of a sturdy conductor so electromagnetic waves will leave the inst and go by the conductor

electromagnetic energy has higher frequency. The electron flows tend to seek the lowest resistance path. thus the mode of energy transmission at higher frequency is radiation rather than conduction.

Because most radiation will be reflected.
Only a little bit goes inside and its energy (photons) will be transferred in more vibrations of the atoms or molecules.
