👉 Concrete light particles, or photons, are fundamental units of electromagnetic radiation that exhibit both particle-like and wave-like properties. These tiny, massless entities carry energy and momentum and travel at the speed of light in a vacuum. Photons are emitted when atoms or molecules transition between energy levels, absorbing or releasing energy in the process. They are responsible for various phenomena, from the glow of stars to the operation of solar panels and fiber optics. Despite their lack of mass, photons can exert pressure on surfaces, known as radiation pressure, and they interact with matter through processes like absorption, reflection, and refraction. Understanding photons is crucial in fields such as quantum mechanics, optics, and astrophysics.
