Wave Behavior at a Boundary 2

A wave machine is used to demonstrate the behavior of a wave at a boundary. An incident pulse is introduced into the left end of the wave machine. It travels through the more dense medium until it reaches the boundary with a less dense medium. At the boundary, both reflection and transmission occur. The reflected pulse is NOT inverted and of about the same length (though a smaller amplitude) as the incident pulse. The transmitted pulse is longer and faster than the incident and transmitted pulse.
