👉 Light particles, often referred to as photons, are fundamental units of electromagnetic radiation and energy. These particles are incredibly small and massless, meaning they have no charge and travel at the speed of light in a vacuum, approximately 299,792 kilometers per second. Photons are the quanta of light, which is the electromagnetic field's smallest discrete excitation. They play a crucial role in various phenomena, from the way we see the world through vision to the operation of technologies like lasers and fiber optics. Unlike matter particles, photons do not interact with each other directly except through the electromagnetic force, making them unique in their behavior and importance in physics.
