What is the relationship between pitch, frequency, and tone in sound waves?

Pitch is the perception of how high or low a sound is, which is determined by the frequency of the sound wave. Frequency refers to the number of vibrations per second in a sound wave, with higher frequencies corresponding to higher pitches. Tone, on the other hand, is the quality or timbre of a sound, which is influenced by the combination of different frequencies present in the sound wave.
