Light sources

 Light sources.

Light comes from different sources. In the day, the Sun gives us light. At night, we use lamps, torches and lights to see.

Here are some light sources.

Remember! The moon reflects light from the Sun. 

It isn't a light source. It's made of rock.

Some light sources are natural and some are artificial. The Sun, fire and lightning are natural light sources. A torch, a lamp and a television are artificial light sources. 

That means they are man-made.
