Physics of light

Light is a form of energy that behaves both as a wave and as particles called photons. It travels through space at an incredible speed, enabling us to see the world around us. Light waves have different wavelengths, which determine their color; shorter wavelengths appear violet, longer ones appear red. When light interacts with objects, it can be reflected, absorbed, or transmitted, shaping our perception of color and brightness. Its dual wave-particle nature explains phenomena like interference, diffraction, and the photoelectric effect, forming the foundation of optics and many modern technologies.
