1. Homework Statement
A radio-frequency EM plane wave propagates in the +z-direction. A student finds that her portable radio obtains the best reception of the wave when the antenna is parallel to the x--y plane making an angle of 60 degrees with respect to the y-axis .
(a) Consider an instant when the fields are non-zero at the location of the antenna.
Draw and lable the direction of the electric field and the direction og the magnetic field.Explain
(b)How would your answers to part a be different if the wave were propagating in the -z-direction.Explain


3. The Attempt at a Solution
a) i drew the E field parallel to the antenna and the b field perpendiculat to it so that the oscillation will be at a max...is this right?
b) i am unsure of what changes

I don't think anything changes if you reverse the direction between +z and -z.

The e and the h waves are still perpendicularly polarized with respect to the orientation of the antenna is my understanding.
