Definition of Natural Frequency | Chegg.com

The natural frequency is the rate at which an object vibrates when it is not disturbed by an outside force. Each degree of freedom of an object has its own natural frequency, expressed as ω n (omega subscript n). Frequency (omega) is equal to the speed of vibration divided by the wavelength (lambda), .
