To calculate the resonant frequency, multiply the length, width, and height of the cavity, then take the square root of this product. Divide the speed of sound by twice this square root to get the resonant frequency.

**The Cavity Resonance Calculator is a handy tool used to determine the resonance frequency of a cavity based on its dimensions**. This calculation is essential in various fields, including physics, engineering, and telecommunications. Understanding cavity resonance helps in designing efficient devices such as antennas, microwave ovens, and resonators.
