Optical resonators are structures that confine and sustain electromagnetic waves, typically in the form of light, by repeated reflection between mirrors or other boundary conditions. They are fundamental components in lasers and optical cavities, enhancing light-matter interactions and enabling precise control over light properties such as frequency, phase, and intensity.

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.

Light is a form of electromagnetic radiation that is visible to the human eye and is responsible for the sense of sight. It exhibits both wave-like and particle-like properties, known as wave-particle duality, and its behavior can be described by various theories including classical optics and quantum mechanics.

Mirrors are reflective surfaces that create virtual images by reflecting light according to the law of reflection, which states that the angle of incidence equals the angle of reflection. They are used in various applications, from personal grooming and interior design to scientific instruments and optical devices.
