"The nature and significance of light"

Light is a form of electromagnetic radiation that is visible to the human eye, enabling us to perceive the world around us. It travels in waves, exhibiting both particle and wave-like properties, a concept known as wave-particle duality. Light waves vary in wavelength, with the visible spectrum spanning from violet (shorter wavelengths) to red (longer wavelengths). Beyond the visible range, light includes ultraviolet, infrared, and other types of electromagnetic radiation. Light plays a crucial role in various natural and technological processes, such as photosynthesis, vision, and communication technologies like fiber optics.
