Electromagnetic Radiation
Slide2What do Xrays, light, microwaves, radio waves, and infrared have in common?
Slide3EM 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.
Slide4How 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)
Slide5Electromagnetic Spectrum
Electromagnetic radiation is organized by how much energy it carries.
The range of electromagnetic radiation is called the Electromagnetic Spectrum.
