👉 Thoroughly discussing light particles, also known as photons, begins with understanding that light is a form of electromagnetic radiation, which travels through space as oscillating electric and magnetic fields. 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 light energy, meaning they carry discrete packets of energy proportional to their frequency, as described by Planck's equation (E = hν). This particle nature of light explains phenomena such as the photoelectric effect, where light can eject electrons from a material, and is fundamental to quantum mechanics. Unlike matter particles, photons do not have charge or mass in the classical sense but exhibit wave-particle duality, behaving as both waves and particles depending on the experimental context. This duality is a cornerstone of modern physics, bridging classical and quantum descriptions of light.
