## Fundamental Frequency Formula

The following formula is used to calculate a fundamental frequency.

f= v / 2*L

- Where f is the fundamental frequency (hz)
- v is the speed of the wave
- L is the length of the tube the sound wave is traveling through.

To calculate the fundamental frequency, divide the speed of the wave by 2 times the length of the tube.

## Fundamental Frequency Definition

A fundamental frequency is the lowest possible frequency required for a system, usually a tube with sound moving through it, to be resonating.

## Fundamental Frequency Example

How to calculate the fundamental frequency of a tube?

**First, determine the speed of the wave.**Calculate the velocity of the sound wave.

**Next, determine the length of the tube.**Measure the length of the tube.

**Finally, calculate the fundamental frequency.**Calculate the frequency using the formula above.

## FAQ

**What is a fundamental frequency?**

A fundamental frequency is the lowest frequency of the system that is resonating. This frequency is used in both physics and music.

**How is fundamental frequency calculated?**

The fundamental frequency is calculated using the formula f = v/2*L where v is the speed of the sound wave, and L is the length of a tube or device the wave is traveling through.
