A light is a fundamental source of illumination that provides brightness and visibility in our surroundings. It is an electromagnetic radiation that enables us to perceive colors, shapes, and details in the environment. Light plays a crucial role in our daily lives, both functionally and aesthetically.

Physically, light is composed of tiny particles called photons, which travel in waves at a high speed. These waves have different wavelengths, and the combination of different wavelengths gives rise to the various colors we see. The visible spectrum encompasses a range of colors, including red, orange, yellow, green, blue, indigo, and violet.

Light not only allows us to perceive the world visually but also influences our mood and well-being. Bright light is often associated with feelings of alertness, energy, and positivity. It can create an uplifting atmosphere and enhance our productivity and focus. In contrast, dim or soft light is often used for relaxation, creating a cozy and intimate ambiance.
