Longitudinal sound wave

Frequency is measured in hertz. The faster the sound wave oscillates the higher pitch it will have. For example, on a guitar a big heavy string will vibrate slowly and create a low sound or pitch . A thinner lighter string will vibrate faster and create a high sound or pitch.

pitch, in music, position of a single sound in the complete range of sound . Sounds are higher or lower in pitch according to the frequency of vibration of the sound waves producing them.

The number of vibrations per second or frequency determines the pitch of a sound. Frequency is directly proportional to pitch. Higher the frequency, higher the pitch.

Hint: Frequency of a sound is the number of cycles of compressions and rarefactions take place in one unit of time. Pitch tells us about the frequency of the sound . Sound with high frequency has higher pitch then the sound with low frequency.
