👉 Light, often perceived as an invisible form of energy, is understood to consist of particles known as photons. These light particles are fundamental to the nature of electromagnetic radiation and play a crucial role in various physical phenomena. Photons are massless, chargeless particles that travel at the speed of light in a vacuum, carrying energy and momentum. They are the quanta of the electromagnetic field, meaning that light's energy is distributed among these discrete packets rather than being continuous. Photons are emitted and absorbed during interactions with matter, underpinning processes such as photosynthesis, the photoelectric effect, and the behavior of atoms and molecules. Their existence is pivotal in explaining how light interacts with objects, from the reflection and refraction of light in optics to its role in quantum mechanics and the fundamental forces of nature.
