👉 Light, at its core, is composed of particles known as photons, which are massless and exhibit both wave-like and particle-like properties. These particles of light travel through space as electromagnetic waves, but they can also behave as discrete packets of energy called photons. Photons are incredibly small, with masses nearly zero, yet they carry a significant amount of energy proportional to their frequency. This dual nature of light—both particle and wave—is fundamental to understanding phenomena like the photoelectric effect and quantum entanglement. In essence, light particles (photons) are the building blocks that allow us to perceive light and interact with the world around us, from the colors we see to the energy they carry in solar panels and lasers.
