Understanding Light

Understanding light involves recognizing it as both a wave and a particle, allowing it to exhibit behaviors like reflection, refraction, and diffraction. It travels at a constant speed in a vacuum, carrying energy that enables us to see and perceive the world around us. Light consists of electromagnetic waves with varying wavelengths, which determine their color. When it interacts with objects, it can be absorbed, reflected, or transmitted, shaping our visual experience. This understanding helps us grasp phenomena like rainbows, lens operation, and the functioning of optical devices, highlighting light's fundamental role in science and everyday life.
