Here's why:

* Frequency refers to the number of wave cycles that pass a given point in a certain amount of time. It's measured in Hertz (Hz), which means cycles per second.

* Amplitude refers to the maximum displacement of a wave from its equilibrium position. It essentially determines the "height" or "intensity" of the wave.

Think of it this way:

* Frequency is like the speed of a train, determining how many carriages pass by you per minute.

* Amplitude is like the size of the train carriages, determining how much space each carriage takes up.

Changing the size of the carriages (amplitude) won't affect how many carriages pass by per minute (frequency).

In summary: Frequency is determined by the source of the wave, while amplitude can be influenced by factors like the energy of the wave. They are distinct properties that do not directly influence each other.
