What are mechanical waves? What are 2 examples of mechanical waves?
Mechanical waves are waves that require a medium in order to transport their energy from one location to another. The medium can be a solid, liquid, or gas.
Two examples of mechanical waves are:
1. Sound waves - these are waves of pressure that propagate through a medium such as air or water, causing particles of the medium to vibrate and create sound.
2. Seismic waves - these are waves of energy that are generated by the sudden release of energy in the Earth's crust, such as during an earthquake. Seismic waves can travel through the Earth's interior and can be detected by seismographs.
