Resonant Frequency Calculator


About Resonant Frequency Calculator (Formula)

A Resonant Frequency Calculator is a tool used to determine the resonant frequency of a system or object. Resonance occurs when a system is subjected to an external force or vibration that matches its natural frequency, causing it to vibrate with maximum amplitude. This concept is relevant in various fields, including physics, engineering, and electronics.

The formula for calculating resonant frequency varies depending on the specific system, but for a simple mechanical system like a mass-spring system, the resonant frequency is given by:

Resonant Frequency (f) = 1 / (2 * π * √(Mass / Spring Constant))


  • Resonant Frequency (f) is the frequency at which resonance occurs, measured in Hertz (Hz).
  • π (pi) is a constant approximately equal to 3.14159.
  • Mass is the mass of the system or object, typically measured in kilograms (kg).
  • Spring Constant is the stiffness of the spring in the system, measured in newtons per meter (N/m).

To use the Resonant Frequency Calculator formula, follow these steps:

  1. Determine the mass of the system (Mass) in kilograms.
  2. Determine the spring constant (Spring Constant) in newtons per meter.
  3. Plug the values of mass and spring constant into the formula: Resonant Frequency (f) = 1 / (2 * π * √(Mass / Spring Constant)).
  4. Calculate the resonant frequency. The result indicates the frequency at which the system will resonate with maximum amplitude.

Resonant frequency calculations are essential in various applications, such as designing mechanical systems to avoid resonance-induced vibrations and optimizing electronic circuits to achieve desired frequencies. It’s important to consider factors like damping and external forces that can affect the resonant behavior of a system.
