In the picture below
http://www.geo.mtu.edu/rs/back/spectrum/e_mag.gif
a bulb is placed on a wire parallel to the direction of the electric field. The bulb is directly on the x-axis where the two waves cross each other.
1. Would the bulb glow when the wire is parallel to the direction of the electric field?
The wire containing the bulb is now shifted up a distance on the plane of the electric field
2. Would the brightness of the bulb be greater than, less than, or equal to that of the brightness in 1?
Now imagine that the wire with the bulb is rotated 45 degrees so that it is now oriented between the electric and magnetic fields
3. Would the brightness of the bulb be greater than, less than, or equal to that of the brightness in 1?

1. I think that the bulb would light up because the wire is parallel to that of the electric field and perpendicular to that of the magnetic field.
2. I think that the bulb would have the same brightness as in the first question because the orientation of the current carrying wire does not change.
3. I think that the bulb would be less bright than that in case 1 because neither field is in the optimum location to light the bulb.
A good explanation is much appreciated
Thanks
