Tuned Cavity

A tuned cavity refers to a resonant cavity that is designed to resonate at a specific frequency or range of frequencies. It is commonly used in various fields such as physics, optics, and electronics.

In physics, a tuned cavity is often used in experiments involving electromagnetic radiation. It consists of two or more mirrors or reflective surfaces that form an enclosed space. The distance between the mirrors is carefully adjusted to create a standing wave pattern, which allows the cavity to resonate at a specific frequency. This resonance enhances the interaction between the radiation and the cavity, making it useful for applications such as laser cavities and optical filters.

In electronics, a tuned cavity is used in radio frequency (RF) circuits to select and amplify a specific frequency. It typically consists of a resonant circuit, such as an LC circuit or a quartz crystal, that is connected to an amplifier. The resonant circuit is tuned to the desired frequency, allowing it to selectively amplify signals at that frequency while attenuating others. This is commonly used in radio receivers, transmitters, and filters.

Overall, tuned cavities are important components in various scientific and technological applications where precise control of frequency is required.
