  1. Electromagnetic Radiation

  2. What do X­rays, light, microwaves, radio waves, and infrared have in common?

  3. EM Radiation • Radiation can be described as the movement of energy through space. • There are many different sources of radiation that vary by intensity. • The Sun, light bulbs, nuclear reactions, and radon gas, are all sources that produce electromagnetic radiation. • We are constantly bombarded by electromagnetic radiation, most of which we cannot see.

  4. How they travel • Electromagnetic waves do not need a medium to travel through. • This means electromagnetic waves can travel through empty space as well as through mediums like air or water! • Electromagnetic waves also do not lose energy as they travel (unlike mechanical transverse waves which lose some of their energy to their medium)

  5. Electromagnetic Spectrum • Electromagnetic radiation is organized by how much energy it carries. • The range of electromagnetic radiation is called the Electromagnetic Spectrum.
