About the Diagram

Introducing the diagram! Read back and forward between the image at the top of the page and the explanation below!

This diagram introduces sunlight, the light produced by the Sun, the star at the centre of our solar system.

It gathers together some useful facts and introduces some important terms that you can check out in the next section.

Remember that:

  • As the Sun explodes with the force of a billion one-megaton nuclear bombs every second it gives off electromagnetic radiation.
  • Sunlight is a form of electromagnetic radiation.
  • The electromagnetic radiation given off by the sun includes all wavelengths of the electromagnetic spectrum.
  • By the time sunlight has passed through the atmosphere and reaches the ground it contains infrared, visible, and ultraviolet wavelengths of light.
  • Viewed from the ground, sunlight contains a portion of the electromagnetic spectrum.
  • Viewed from outer space, sunlight contains all of the electromagnetic spectrum.
  • Without sunlight, life as we know it would not be possible because it carries the energy that plants need to grow and the heat that keeps the world warm.
