Multiple Choice
If the electric field in a plane electromagnetic wave is along the y axis and its magnitude is given by Em sin (kx + t) in SI units, then the magnetic field is along the z axis and its magnitude is given by:
A) (Em/c) cos (kx + 11ef0130_b6d0_5889_bc85_a96f9c22c0b5_TB6585_11t)
B) -(Em/c) cos (kx + 11ef0130_b6d0_5889_bc85_a96f9c22c0b5_TB6585_11t)
C) (Em/c) sin (kx + 11ef0130_b6d0_5889_bc85_a96f9c22c0b5_TB6585_11t)
D) -(Em/c) sin (kx + 11ef0130_b6d0_5889_bc85_a96f9c22c0b5_TB6585_11t)
E) Em cos (kx + 11ef0130_b6d0_5889_bc85_a96f9c22c0b5_TB6585_11t)
