Case A: A long, thin steel wire is cut in half, and each half is connected to a different terminal of a light bulb. An electromagnetic (EM) plane wave moves past the wire, as shown above.

--------------------------------

Part 1)

In what direction is the wave propagating?

+ x - x + y - y + z Other

--------------------------------

Part 2)

Would the bulb glow in this case?

Yes No

--------------------------------

Part 3)

Suppose instead that the wire were positioned as described below. Would the brightness of the bulb in each case below be greater than, less than, or equal to the brightness that it had in Case A?

Case B: The wire is parallel to the y-axis but with its bottom end located on the x-axis (i.e., the wire is shifted upward a distance equal to half its length).

greater than the brightness in Case A less than the brightness in Case A equal to the brightness in Case A

--------------------------------

Part 4)

   

Case C: The wire is tilted so that it makes an angle of 40^o with respect to the y-axis but is still parallel to the y-z plane.

   

greater than the brightness in Case A less then the brightness in Case A equal to the brightness in Case A

Please explain as much as you can. I think I have part 1 & 2 as +x and no. Is this correct? I really have no idea about the last two parts. Thanks.
