rezonánsfrekencián

Rezonánsfrekvencia, also known as resonant frequency, is a specific frequency at which a system, such as a mechanical, electrical, or optical system, tends to oscillate with greater amplitude than at other frequencies. This phenomenon occurs when the system's natural frequency matches the frequency of an external force or stimulus.

In mechanical systems, such as a tuning fork or a bridge, the resonant frequency is the frequency at which the system vibrates most strongly. This can lead to destructive interference if the amplitude of vibration becomes too large, potentially causing the system to fail.

In electrical systems, such as an LC circuit or a radio receiver, the resonant frequency is the frequency at which the circuit's impedance is minimized. This allows for maximum power transfer and efficient operation of the system.

In optical systems, such as a Fabry-Perot interferometer or a laser cavity, the resonant frequency is the frequency at which the system's transmission or reflection is maximized. This allows for selective filtering or amplification of specific frequencies.

The resonant frequency of a system is determined by its physical properties, such as mass, stiffness, and damping, as well as the external forces or stimuli acting on it. By understanding and controlling the resonant frequency, engineers and scientists can design and optimize systems for various applications, from musical instruments to communication devices.
