=When a wave moves from one medium into another, does all the energy continue to propagate in the same direction? =

When a wave moves from one medium into another, its direction of propagation changes. In addition to the transmitted wave continuing from one medium into another, there is also a reflected wave back into the original medium. As the energy is moving throughout the wave, the direction of propagation changes because as energy is exerted,
