👉 Light, often perceived as a form of energy or a wave, can also be understood as composed of particles known as photons. These light particles are fundamental to explaining phenomena such as the photoelectric effect and the behavior of light in various media. While light waves describe its propagation through space, photons represent discrete packets of energy that travel at the speed of light. This dual nature—both wave-like and particle-like—is a cornerstone of quantum mechanics, illustrating how light can exhibit properties of both. Photons are essential in understanding not only the behavior of light but also its interactions with matter, from the emission and absorption of light in atoms to the functioning of solar cells and fiber optics. Thus, the term "light particles" encapsulates this dual perspective, highlighting the particle aspect that underpins much of modern physics.
