photon sources

Photon sources are devices that produce light particles called photons, which are the basic units of electromagnetic radiation. These sources include natural ones like the sun, and artificial ones such as lasers and LED lights. They work through mechanisms like heating, electrical excitation, or quantum processes to emit photons at specific wavelengths or colors. Photon sources are essential in many applications, including communications, medical imaging, and scientific research, providing controlled, reliable light emission for various technological and practical uses.
