👉 Light particles, also known as photons, are fundamental elements of light and 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 quanta of electromagnetic energy, meaning they carry discrete packets of energy proportional to their frequency. They exist in various states of energy, from zero (the vacuum state) to high-energy states that correspond to visible light, X-rays, and other forms of electromagnetic radiation. Despite their lack of mass, photons exhibit properties of both particles and waves, such as being able to be absorbed, emitted, and reflected, making them crucial in understanding phenomena like the photoelectric effect, where light can eject electrons from a material, and in the behavior of lasers, which produce highly coherent and monochromatic light.
