Light Light is a form of electromagnetic radiation that is visible to the human eye. It consists of photons, which are particles of light that travel in waves at various wavelengths along the electromagnetic spectrum. Light plays a fundamental role in optics, physics, and everyday life, serving as a primary source of illumination, enabling vision, and driving photosynthesis in plants.

Light exhibits properties such as reflection, refraction, diffraction, interference, and polarization, making it a versatile and powerful tool in various applications, including lighting, imaging, communication, sensing, and laser technology. Different light sources, such as incandescent bulbs, fluorescent lamps, LEDs, lasers, and natural sunlight, emit light at different wavelengths and intensities, giving rise to a diverse range of colors, brightness levels, and spectral characteristics.
