Now You Know

After completing this tutorial, you will be able to complete the following:

  • Define electromagnetic waves as waves that consist of electric and magnetic components.
  • Give one source for each type of electromagnetic wave.
  • Explain that different types of waves (such as radio waves, light and X-rays) in the electromagnetic spectrum have different wavelengths.

Everything You'll Have Covered

There are many different types of waves we encounter in our daily lives. An electromagnetic wave is a wave composed of electric and magnetic waves and includes a range of wavelengths we call the electromagnetic spectrum. Starting from the longest wavelengths, the spectrum includes radio, microwaves, infrared waves, visible waves, ultraviolet waves, x-rays and gamma rays. These different wavelengths have very unique properties and serve a useful purpose in our lives.

All the waves in the electromagnetic spectrum travel at the speed of light. Waves carry energy, and the amount of energy depends on the wavelength. The smaller the wavelength, the more energy the wave carries.
