* For waves like light and electromagnetic waves, energy is directly proportional to frequency. The higher the frequency, the higher the energy. Amplitude does not affect the energy of these waves.
* For mechanical waves, like sound waves, energy is proportional to the square of the amplitude. This means that a wave with double the amplitude carries four times the energy.
In summary:
* For all waves, amplitude is related to energy, but not always directly.
* For light and electromagnetic waves, frequency determines energy.
* For mechanical waves, amplitude squared determines energy.
