Powered by Froala Editor

Artificial sources of light are man-made. People create or build them to provide light, especially when it is dark or when natural light is not available.

Here are four good examples:

1. Electric Bulbs

These include incandescent bulbs and LED bulbs.

They use electricity to produce light.

Common in homes and schools.

2. Candles

Produce light through burning (combustion) of wax.

Used during power outages or for decoration.

3. Torches/Flashlights

Use batteries to power small electric bulbs.

Handy during camping or emergencies.

4. Fluorescent Tubes

Long tubes found in offices, homes, and classrooms.

Use a gas and electricity to give off light.
