4. We are given the voltage of an electromagnetic wave that is traveling along a transmission line. This expression for the voltage wave, where z is the distance from generator in meters, can be written as; v(z, t) = 10ea² sin(4ñ × 10ºt - 40лz) (Volts) (a) Find the frequency, wavelength, and phase velocity of the wave. (b) At z = 5 m, the amplitude of the wave was measured to be 2 Volts. Find a. (c) Write the attenuation coefficient a in terms of decibels per meter (dB/m). (d) Is this voltage wave time harmonic? If so, write the mathematical phasor form of this voltage wave.
