👉 Light particles, also known as photons, are fundamental entities that exhibit both wave-like and particle-like properties, forming the basis of quantum mechanics and electromagnetic theory. 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 radiation, meaning they carry discrete packets of energy proportional to their frequency, as described by Planck's equation (E = hf). This duality—being both particles and waves—explains phenomena such as the photoelectric effect, where light can eject electrons from a metal surface, and interference patterns in experiments like the double-slit experiment. Photons are crucial in various fields, including optics, quantum computing, and astrophysics, where they help explain the behavior of light across the electromagnetic spectrum, from radio waves to gamma rays.
