1. The document describes a plane electromagnetic wave propagating along the negative z-direction in free space with a frequency of 100 Hz. 2. The maximum amplitude of the electric field is 1 V/m and is observed at t=0 and z=-12cm. 3. The magnetic field expression for the instantaneous magnetic field is B(z,t) = 0.326 Cos(1.257x10^8*t - 4.19z) mT.
