The voltage of an electromagnetic wave traveling on a transmission line is given by v(z,t) = Se^(-jÏ‰t-Î²z), where z is the distance in meters from the generator. a) Find the frequency, wavelength, and phase velocity of the wave. b) At z = 2 m, the amplitude of the wave was measured to be 2V. Find the phase angle.
