Enter the speed of the wave and the length of the tube the wave is traveling through into the calculator to determine the fundamental frequency of the tube. This calculator can also determine the wave speed or length given the other variables.

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?

  1. First, determine the speed of the wave.

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.
