(a) The voltage is maximum at the input terminals (A).
(b) One-quarter wavelength away, the voltage drops to zero (B).
(c) Beyond B, the voltage again increases but in opposite phase.
(d) The voltage at the output terminals (C) has the same amplitude
as the voltage at A, but is 180 degrees out of phase with it.
