        The Electromagnetic Spectrum: FRONTLINE

        The electromagnetic spectrum allows physicists to classify different types of electromagnetic waves on the basis of their wavelengths and frequencies. What determines the wavelength and frequency of a given wave and distinguishes one wave on the spectrum from another is the amount of energy each wave carries -- specifically, the level of energy in the photons of each. This video segment adapted from FRONTLINE explores the different types of radiation represented by electromagnetic waves and how their properties vary.

        This video is available in both English and Spanish audio, along with corresponding closed captions.
