👉 Light particles, or photons, are fundamental entities that constitute light and other forms 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 created when energy is emitted or absorbed by atoms or molecules, and they carry discrete packets of energy proportional to their frequency, as described by Planck's equation. This particle nature of light explains phenomena such as the photoelectric effect, where light can eject electrons from a material, and it also underpins our understanding of wave-particle duality, where light exhibits both wave-like and particle-like properties depending on the experimental context.
