Answer

Understanding Natural vs. Artificial Light Sources
When distinguishing between natural and artificial sources of light, it is essential to understand what each term means.
Natural Light Sources
Natural light comes from elements that occur in nature, without human intervention. The most significant source of natural light is the Sun, which provides illumination during the day.
Examples of Natural Light Sources
- Sun: The Sun is the primary source of natural light on Earth. It emits light through nuclear reactions happening in its core, making it essential for life.
Artificial Light Sources
Artificial light is created by humans using various technologies. This includes anything that requires electricity to produce light.
Examples of Artificial Light Sources
- Candle: Although a candle produces light, it is still considered an artificial source because it requires materials (wax, wick) and is not a naturally occurring light source.
- Electric Bulb: Electric bulbs are entirely artificial, relying on electricity to illuminate.
- Torch: A torch is another artificial light source, typically powered by batteries.
Conclusion
In the context of the options provided, the Sun is the only natural source of light. Therefore, option 'B' (Sun) is the correct answer. Understanding the difference between natural and artificial light can help us appreciate the importance of natural light for our environment and daily activities.
