The figure (http://tinypic.com/r/vo5ssm/6) shows the time variation of the magnitude of the electric field of an electromagnetic wave produced by a wire antenna. What is the magnitude of the electric field at t = 3.34 × 10−10 s? What is the magnitude of the magnetic field at t = 6.0 × 10−9 s and at t = 6.67 × 10−10 s? I keep looking throughout the chapter to figure some kind of equations. The only ones I see are u=ε0E^2, the doppler effect, and polarization.. Please help with a good explanation of the answers.
