What is the formula of resonating frequency?

In physics, resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies . [ example ] A familiar example is a playground swing, which acts as a pendulum.

Therefore, the resonant frequency can be derived by expressing the equal value of both capacitive and inductive reactance as follows: X L = X . 2ℼfL = 1/ (2ℼfC) f r = 1/ (2ℼ √LC) 17 Mar 2022

Techniques used to confirm a resonance Impact test: One of the most commonly used methods for measuring a system’s natural frequency is to strike it with a mass and measure the response . This method is effective because the impact inputs a small amount of force in the equipment over a large frequency range.
