Definition
- Noun:
- A system that resonates: A resonator is any physical system or object that naturally oscillates at specific frequencies when excited.
- An electrical circuit for oscillation: In electronics, a resonator is a circuit containing both capacitance (C) and inductance (L) designed so that an electrical oscillation reaches its maximum strength at a particular frequency.
- A hollow chamber for waves: A resonator is an enclosed space or cavity whose size and shape allow sound waves or electromagnetic waves (like microwaves) to build up to a strong vibration at certain resonant frequencies.
Examples of Usage
- Noun:
- The guitar's body acts as a resonator, amplifying the sound of the strings.
- The engineer designed a quartz crystal resonator to control the clock's frequency precisely.
- In the laboratory, they used a microwave resonator to conduct the experiment.
Advanced Usage
"Cavity resonator": A specific type of resonator that is a hollow, enclosed space used to resonate electromagnetic waves, common in microwave technology and lasers.
- The klystron tube uses a cavity resonator to generate radio waves.
"Helmholtz resonator": A specific acoustic resonator consisting of a rigid container with a small opening, used to amplify or absorb specific sound frequencies.
- The bottle acts as a Helmholtz resonator when you blow across its top.
