A resonant cavity is a hollow space surrounded by conductive walls that allows electromagnetic waves to resonate at specific frequencies, amplifying them through constructive interference. It is a fundamental component in devices like lasers, microwave ovens, and particle accelerators, where precise control of electromagnetic wave frequencies is crucial.

Electromagnetic waves are oscillations of electric and magnetic fields that travel through space at the speed of light, encompassing a broad spectrum from radio waves to gamma rays. They do not require a medium to propagate and are fundamental to many technologies, including communication, imaging, and energy transfer.

Constructive interference occurs when two or more waves superimpose to produce a wave with a larger amplitude than the individual waves. This phenomenon is fundamental in understanding wave behavior, leading to applications in fields such as acoustics, optics, and quantum mechanics.

Microwave ovens use electromagnetic radiation in the microwave frequency range to heat and cook food by causing water molecules to vibrate, producing thermal energy. They offer a quick and efficient cooking method, preserving nutrients better than some traditional methods, but can sometimes result in uneven heating or texture changes.
