👉 The butterfly, often symbolically associated with light particles, refers to the fundamental constituents of light itself, which are photons. Photons are massless, point-like particles that carry energy and momentum, making them the primary carriers of electromagnetic radiation, including visible light. In a broader context, the concept of "light particles" can also extend to quantum field theory, where light is described as being composed of these discrete packets of energy, or quanta. These photons interact with matter and other photons through electromagnetic forces, enabling phenomena such as reflection, refraction, and absorption. The idea of light as composed of these tiny particles not only explains the wave-particle duality observed in light but also underpins much of modern physics, from quantum optics to cosmology.
