Optics and photonics are fields of science and engineering that focus on the behavior and properties of light. Optics studies how light interacts with different materials, including reflection, refraction, and dispersion. This knowledge is essential for designing lenses, mirrors, and other optical devices used in everyday applications like glasses and cameras. Photonics extends the principles of optics to the generation, manipulation, and detection of photons, which are particles of light. This field plays a crucial role in technologies such as fiber optics for telecommunications, laser systems for medical procedures, and various imaging techniques used in science and industry.
