👉 Light particles, often referred to as photons, are fundamental quanta of electromagnetic radiation. These particles are massless and travel at the speed of light in a vacuum, approximately 299,792 kilometers per second. Photons are the smallest units of light energy and can exist independently or be emitted or absorbed by atoms and molecules. They carry energy and momentum, which is crucial for various phenomena such as photosynthesis, the operation of solar panels, and the functioning of optical devices like lasers and fiber optics. Unlike matter particles, photons do not have an intrinsic charge and their interactions with matter are primarily through electromagnetic forces, making them essential in understanding light's behavior and its role in physics and everyday life.
