The phenomenon where a system vibrates with greater amplitude at one frequency is called what?

The correct term for the phenomenon where a system vibrates with greater amplitude at a specific frequency is resonance. Resonance occurs when an external force or influence matches the natural frequency of a system, leading to an increase in the amplitude of oscillations. This can be observed in many physical systems, such as musical instruments, bridges, and even in hearing aids, where certain frequencies may be amplified more than others due to the system’s design and materials.

In contrast, oscillation refers to any repetitive variation, typically in time, of some measure about a central value. Wavelength is a term used to describe the distance between successive crests of a wave, which is not the same as the phenomenon of resonance. Phase indicates the position of a point in time on a waveform, which is unrelated to the specific increase in amplitude associated with resonance. Understanding resonance is crucial in various fields, especially in audio engineering and acoustics, where it can significantly affect sound quality and auditory perception.
