👉 Light particles, often referred to as photons, are fundamental entities in quantum physics that represent packets of electromagnetic energy. Unlike matter particles such as electrons or protons, which have mass and occupy specific positions in space, light particles are massless and exhibit both wave-like and particle-like properties—a phenomenon known as wave-particle duality. In a volume context, the concept of "light particles" can be visualized as tiny bursts of energy that travel through space at the speed of light. When these particles are confined to a specific volume, they can interact with matter, absorb or emit energy, and contribute to phenomena like scattering, reflection, and refraction. For example, in a dense medium like water or glass, light particles (photons) can be scattered by molecules, changing their direction and sometimes their wavelength, which is why the sky appears blue or how light bends when it passes through different layers of the atmosphere. The volume of space occupied by these particles is minuscule but significant in understanding how light propagates and interacts with matter at a fundamental level.
