When you strike a tuning fork, it produces a sound wave.
If you strike it harder, the wave will have the same frequency (determined by the length of the tines), but will have a greater amplitude, because the vibrations are more intense.

If you strike it harder, the wave will have the same frequency (determined by the length of the tines), but will have a greater amplitude, because the vibrations are more intense.
You can demonstrate this principle easily by turning up the volume control on a radio. This amplifies the sound waves without changing the frequency.
