Consider a time-varying electric field intensity E = E cos(wt - Bz) that exists everywhere in free space. Use
Faraday's law to determine the corresponding magnetic field intensity H. You may assume there is no DC
(constant) component. Use Ampère's law on your expression for H to find E and solve for ß in terms of w.
