Asinusoidal beam of electromagnetic radiation that is only 2 cm high propagates in the +x direction, with the electric field in the ±z direction. the beam strikes a metal rod that is centered on the origin and aligned along the z axis.
you place detectors sensitive to electromagnetic radiation at location ⟨0,−17,0⟩ m (detector a) and location ⟨0,0,17⟩m (detector b).

answer the following questions for detector a and for detector b: will the detector detect electromagnetic radiation?

if so: what is the direction of the magnetic field in the radiation?
