Energy and Waves. If you’ve ever been in a stadium when they did the wave you probably saw that waves have a lot of energy ! Of course a physics wave and a stadium wave are not really the same thing.
Work causes displacement along a vector. If wave A causes exactly opposite displacement to wave B the waves will fully cancel (they do not form a standing wave!). This is not because energy has been lost. Its because you have combined negative and positive energy to create zero energy. Conservation of energy is not violated because -1 + 1 = 0.
Thinking about potential energy can help us understand why tsunamis can be so damaging. When a tsunami approaches the shore it shoals (becomes much higher) so the water particles are displaced further from equilibrium. They acquire a lot of potential energy and this is released when the wave interacts with land.
The wave speed depends on the tension in the string and the linear mass density of the string. A section of the string with mass \(\Delta\)m oscillates at the same frequency as the wave . The total mechanical energy of the wave is the sum of its kinetic energy and potential energy .
If you toss a pebble in a pond the surface ripple moves out as a circular wave. As the ripple moves away from the source the amplitude decreases. The energy of the wave spreads around a larger circumference and the amplitu…
