👉 Electronics-light particles, often referred to as photons, are fundamental components of the electromagnetic spectrum, which includes all forms of electromagnetic radiation. Photons are massless particles that exhibit both wave-like and particle-like properties, a duality central to quantum mechanics. They are the quanta of light, the smallest discrete packets of electromagnetic energy. When an electron in an atom or molecule transitions between energy levels, it either absorbs or emits a photon whose energy corresponds precisely to the difference between these levels. This process underpins various phenomena, from the colors we see in nature to the operation of solar cells and fiber optics. Photons interact with matter through processes like absorption, reflection, refraction, and emission, making them crucial in technologies such as lasers, LEDs, and photodetectors. Understanding photons is essential for grasping how light travels and interacts with electronic devices, bridging the gap between classical physics and quantum mechanics.
