Electrical Conductor is in relation to heat transfer

[Dreebs]

Homework Statement

One of the two glass panes in each window is coated with a transparent electrical conductor. Why does this coating improve the window's insulating ability?
Select one:
a. The transparent conductor is black in the infrared, with a low-temperature emissivity of almost 1.
b. Electrical conductors are good thermal insulators.
c. Little heat can flow between the two panes by thermal radiation. The transparent conductor reflects infrared light, so that the coated pane is unable to emit its own thermal radiation and the uncoated pane see a reflection of its thermal radiation.
d. The transparent conductor is a poor conductor of heat.

Homework Equations

N/A

The Attempt at a Solution

C, due to the coating heat is reflected and the window itself is unable to emit large quantities of thermal radiation

Think eddy current generation. But be doubtful; just a WAG.

I'm sorry, I don't understand what you mean.

How does magnetic shielding work at high frequencies with conducting (not necessarily magnetic) shields?

My hint was not very good.

So - have you studied the effects of plane e-m waves at an air-conductor interface In particular, what is the attenuation coefficient inside the conductor?

Yeah, this is super basic physics. I have a feeling you may be overthinking the question. We haven't covered any of that in class.

Yes, but even if you haven't had to delve into the gory details (it would be an advanced undergraduate course to do so) yet you were asked the question so you must have been given at least a broad idea of what happens to an electromagnetic wave traveling thru a metal?
