Imagine that we have a transmitter of microwaves that radiates a linearly polarized wave whose -field is known to be parallel to the dipole direction. We wish to reflect as much energy as possible off the surface of a pond (having an index of refraction of 9.0). Find the necessary incident angle and comment on the orientation of the beam.
