LIGHT

Light makes the world seem bright and colourful to our eyes.

• Light is a type of electromagnetic radiation that carries energy from a source (something that makes light) at the very high speed of 300,000 kps (186,000 miles per second, or 670 million mph).
• Light rays travel from their source in straight lines.
• Although they can pass through some objects, they bounce off others or pass around them to make SHADOWS.
