👉 Elsewhere, light particles, often referred to as photons, are fundamental entities that constitute electromagnetic radiation. These particles are incredibly small and massless, traveling at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. Photons are the quanta of light, meaning they carry discrete packets of energy proportional to their frequency, as described by Planck's equation. They interact with matter through various processes such as absorption, emission, and scattering, but unlike matter particles, photons do not have charge or mass in the classical sense. This unique nature allows them to exhibit both wave-like and particle-like properties, a phenomenon known as wave-particle duality. In essence, wherever light encounters matter, these elusive particles play a crucial role in phenomena ranging from photosynthesis to the functioning of solar cells and optical communications.
