Sources of Light:
Sources of light are objects that emit light, allowing visibility of both the light-emitting object itself and the surrounding environment. These sources can either be natural or artificial.
- Natural Sources of Light: Natural sources of light are those that appear in nature and are not man-made. The sun is the main natural source of light during the daytime. It helps in lighting up the earth. Other stars that we see in the night sky also emit light, just like the Sun. Some animals and plants can also produce light naturally, a process called bioluminescence. For example, fireflies, anglerfish, honey mushrooms, etc.
- Artificial Sources of Light: Artificial sources of light are man-made objects designed to emit light in the absence of natural light. For example, electric bulbs, torchlight, tubelight, LED, etc.
