PS4.B: Electromagnetic Radiation

 

In this video Paul Andersen describes some of the properties of electromagnetic radiation.  The electromagnetic spectrum varies by wavelength from radio waves to gamma rays.  We only see a portion of the spectrum known as visible light.  A number of phenomenon (including refraction, emission spectrums, and gamma radiation) are discussed.  A teaching progression K-12 is also included.
