A lossless transmission line has characteristic impedance Z₀=50Ω. It is 80 m long and connected at one end to a source of

v=120cos(2πft)

and at the other a load of 80Ω.

Suppose the operating frequency f is 60 Hz with a propagation velocity up=2c/3, where c is the speed of light. Find the wavelength of the signals on the traveling wave. Compare it with the length of the line. Find the voltage across the load.
