Q:

# What has a higher frequency than the fundamental frequency?

A:

In acoustics, the harmonics of a sound all have a higher frequency than the fundamental frequency. The fundamental frequency is the lowest resonant frequency that a sound generator produces.

Harmonics are whole-number factors of the fundamental frequency. For example, the second harmonic has a frequency that is double that of the fundamental, while the third harmonic is triple the frequency.

Any object that vibrates at a regular frequency, such as a guitar string or the air in a brass instrument, generates a harmonic frequency structure.

Sound quality, or timbre, depends on the frequency and distribution of the harmonics, as well as the different media that give rise to these vibrations.

The difference between pitch and volume is that pitch is determined by the frequency that sound waves vibrate at while volume measures how loud or soft sound is. Combined with timbre, pitch, measured in hertz, and volume, measured in decibels, comprise the three components of sound.

The frequency of a sound is the rate at which wave crests reach a given point. Sound waves propagate outward from their source, as a series of compressions and rarefactions of the surrounding air. The peak of each cycle can be plotted as the crest of a wave, as can the low point or trough. The frequency with which these crests and troughs arrive gives sound its pitch.

The fundamental frequency of a closed tube that is 35 centimetres long is approximately 246.4 Hertz, assuming sound is traveling at 345 metres per second. The formula for obtaining this number is f(1)=nv/4L.
