This video shows a simulation of a wave propagating in a waveguide. We can clearly see the reflected wave going backwards at the end due to the impedance mismatch at the exit of the waveguide

this channel has cool visualizations, including similar simulation of optic fibers, with a comparison of monomode and multimode propagation. very cool!
