When a mechanical wave is partially reflected and partially transmitted, it becomes two waves. What happens to the energies of the two waves?

• Each wave will have less energy than the original wave.

• Each will have more energy than the original wave.

• Each will have the same energy as the original wave.

• One will have the same energy and the other will have less energy.

• The wavelength has increased.

• The amplitude has decreased.

• The wave speed has slowed down.
