👉 Light particles, also known as photons, are fundamental entities that exhibit both wave-like and particle-like properties, playing a crucial role in various physical phenomena. These particles of light are massless and have no electric charge, making them distinct from other subatomic particles like electrons or protons. 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 = hν). This particle nature is evident in processes such as the photoelectric effect, where light hitting a metal surface ejects electrons, demonstrating that light can behave as discrete particles. Additionally, photons are responsible for phenomena like reflection, refraction, and diffraction, which are typically explained through wave theory but can also be understood in terms of individual photon interactions. The study of light particles is essential in fields ranging from optics and quantum mechanics to astrophysics and telecommunications, where understanding the behavior of photons is key to developing technologies like lasers and fiber optics.
