Question:

At a particular instant of time, a light beam traveling in the positive z direction has an electric field given by E̅ = (6.22 N/C)x` + (2.87 N/C)y`. The magnetic field in the beam has a magnitude of 2.28 × 10-8 T at the same time.

(a) Does the magnetic field at this time have a z component that is positive, negative, or zero? Explain.

(b) Write B̅ in terms of unit vectors.
