These are animations of a voltage wave traveling along a lossless
transmission line with the stated termination

Short Termination (Z_{L} = 0 Ω)

Notice that, for a short circuit termination, all of the
voltage wave is reflected, with a phase shift of 180º (Γ =
-1). Also note that, at the location of the short (on the far
right), the voltage is always zero.

Open Termination (Z_{L} = ∞)

Notice that, for an open circuit termination, all of the
voltage wave is reflected, with a phase shift of 0º (Γ =
1). Also note that, at the location of the short (on the far
right), the voltage maximum is twice the magnitude of the incoming
wave.

Matched Load Termination (Z_{L} = Z_{o})

Notice that, for a matched load termination, none of the
voltage wave is reflected, and all the power coming down the
line is passed to the load.
