1. Suppose that the wire were oriented parallel to the z-axis.
As the wave propagates past the wire, would the electric field due to the radio wave cause the charges in the wire to move? If so, would the charges move in a direction along the length of the wire? Explain.
As the wave propagates past the wire, would the magnetic field due to the cause the charges in the wire to move in a direction along the length of the wire? Explain.
2. Imagine that the thin conducting wire is cut in half and that each half is connected to a different terminal of a light bulb. (See diagram at right.)
If the wire were placed in the path of the radio wave and oriented parallel to the z-axis, would the bulb ever glow? Explain. (Him: Under what condition can a bulb glow even if it is not part of a closed circuit?)
How, if at all, would your answer change lithe wire were oriented:
• parallel to the y-axis? Explain.
• parallel to the x-axis? Explain.
3. Suppose that the bulb were disconnected and that each half of the wire were connected in a circuit, as shown. (A conducting wire or rod used in this way is an example of an antenna.)
In order to best detect the oncoming radio wave (that is. to maximize the current through the circuit), how should the antenna be oriented relative to the wave? Explain.

I Review
Laboratory scientists have created the electric and
magnetic fields shown in (Figure 1). These fields are also
seen by scientists that zoom past in a rocket traveling in
the x-direction at 1.0 x 106 m/s. Assume that B =
0.52 T and E = 1.2x106 V/m.

SECTION A
You must answer ALL questions in this Section.
1. Explain (with specific reference to Maxwell's equations) why a traveling wave in the
electric field must always be associated with a propagating wave in the magnetic field.
2. Explain why a free charge q will be attracted to the surface of an electrically neutral
conductor, and explain how you expect this force to vary with distance compared to
the regular Coulomb force between two charges.
3. Explain how you could estimate the refractive index of glass given a power supply,
a sheet of glass, two flat pieces of metal, some wire and appropriate instruments for
measuring the properties of electrical circuits.
4. With reference to one or more of Maxwell's equations, explain why it is apparently
impossible to find a static magnetic field which has a "porcupine" configuration - that
is, a surface at which all the field vectors are pointing in the outward direction.

A snapshot graph of an EM plane wave is shown below. The electric field is parallel to the y-axis and the magnetic field is parallel to the z-axis. The points labeled 1, 2 and 3 are in the(x, y) plane.
Rank the magnitude of the magnetic field at points 1, 2 and 3. If field is 0 at any of thesepoints, state so explicitly. Explain
What is the direction of propagation of the plane wave? Explain
If the wavelength of the plane wave is λ = 600 nm and the magnitude of the electric field is E= 10 V/m, write an expression for the B field in the form B = B sin(Cx + Dt) .Give the values of Bo, C and D.Take for the speed of light c = 3x10 m/s
