👉 Light particles, often referred to as photons, are fundamental entities that constitute electromagnetic radiation, including sunlight. These particles are incredibly small, far smaller than atoms or molecules, and travel at the speed of light in a vacuum, approximately 299,792 kilometers per second. Photons are massless and have no electric charge, making them unique among subatomic particles. They carry energy and momentum, and their interactions with matter underpin many phenomena, from the way we see the world through vision to the functioning of solar cells and the behavior of stars. In essence, light particles are the building blocks of electromagnetic waves, which encompass a broad spectrum including visible light, ultraviolet, X-rays, and more, each with distinct properties and applications.
