👉 Light particles, also known as photons, are fundamental entities that make up light and other forms of electromagnetic radiation. These particles are incredibly small and massless, meaning they have no electric charge and cannot be directly observed under normal conditions. Photons travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. They carry energy and momentum, and their interactions with matter—such as absorption, emission, or reflection—are crucial for various physical phenomena, including the way we see the world around us. For instance, when sunlight hits your eyes, photons from the light particles are absorbed by photoreceptor cells, initiating a series of chemical reactions that ultimately allow you to perceive colors and light. Despite their minuscule size, photons play a vital role in both natural processes and technological applications, from photosynthesis to fiber optics and solar energy.
