PS4B - 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.
