Homonym: light (Illumination)
Light is a form of energy that allows us to see the world around us. It travels in waves and can come from various sources, such as the Sun, light bulbs, and fireflies. When light hits an object, it can be absorbed, reflected, or transmitted, which helps create the colors and shapes we perceive.
In addition to helping us see, light plays a crucial role in many natural processes. For example, photosynthesis in plants relies on sunlight to convert carbon dioxide and water into food and oxygen. This process is essential for life on Earth, as it provides energy for plants and, ultimately, for the animals and humans that depend on them.
