key term - Fundamental frequency

Citation:

Definition

Fundamental frequency is the lowest frequency at which a system oscillates. It is also known as the first harmonic and serves as the basis for higher harmonics.

5 Must Know Facts For Your Next Test

  1. 1. The fundamental frequency is determined by the physical properties of the oscillator, such as length, tension, and mass density.
  2. 2. In a standing wave pattern, the fundamental frequency corresponds to the simplest mode of vibration.
  3. 3. The relationship between wavelength ($\lambda$) and fundamental frequency ($f_0$) can be expressed as $v = f_0 \lambda$, where $v$ is the wave speed.
  4. 4. For a string fixed at both ends, the fundamental frequency can be calculated using $f_0 = \frac{1}{2L} \sqrt{\frac{T}{\mu}}$, where $L$ is the length of the string, $T$ is the tension, and $\mu$ is the linear mass density.
  5. 5. Fundamental frequency plays a crucial role in musical instruments and acoustic engineering for determining pitch and sound quality.
