Wave Energy of Mechanical Waves
In typical mechanic waves such as sound and water, what is
the energy of the wave proportional to? For example,how do you
recognise a high energy wave at the beach??
For a water wave:
Wave power is proportional to the wave period and to the square of the wave
The calculation of power in water waves is presented at this URL:
You can generally recognize a high energy wave at the beach by its level of
There are a couple of ways to express the energy of sound waves.
Please refer to the following URL for a precise discussion of sound wave
When talking about the energy of sound waves
You can talk about sound intensity, power, and/or energy.
Everything else being equal, energy is proportional to amplitude or
the size of the wave.
