In 1678, Christiaan Huygens (1629-1695) published Traité de la Lumiere, where he argued in favor of the wave nature of light. Huygens stated that an expanding sphere of light behaves as if each point on the wave front were a new source of radiation of the same frequency and phase.

1) Have students use a textbook or an encyclopedia to build a timeline of the history of theories about the nature of light since the 1600s. Working either as a class or individually, have students place the following individuals on the timeline, together with a 2-3 sentence summary of each theory about the nature...

Electromagnetic radiation, or light, is a form of energy. Visible light is a narrow range of wavelengths of the electromagnetic spectrum. By measuring the wavelength or frequency of light coming from objects in the universe, we can learn something about their nature.
