A vertically oriented wire experiences an alternating current that makes it first positively charged and then negatively charged, repeated 6 x 10° times a second. The peak current that flows as it is charging is 25 milliamps. A second vertical, identical wire is 100 m away, and is being charged, at the same time and in the same way as the first wire is so the two wires are in phase. B 14. Midway between the two wires, the total Intensity of the electromagnetic radiation there is (A) twice that of either wire (B) 4 x that of either wire (C) zero (D) the same as the intensity of either wire A 15 The electromagnetic wave emitted by the first wire is (A) vertically polarized (B) horizontally polarized (C) unpolarized (D) you can't tell 16. Midway between the two wires, what can you say about the total magnetic field? (A) It is twice the value of either wire (B) it is 4 x the value of either wire (C) it is zero (D) it is one half the value of either wire 17. To allow the first wire to emit more photons per second while not changing its power output I should (A) increase the frequency (B) decrease the frequency (C) you can't change the number of photons if you don't change the power 1 The two wires (A) attract (B) repel (C) alternately attract and repel (D) have no effect.
