Document Summary

A type of radiation energy that travels through space ( a vacuum) as waves at the speed of light ( 3. 00x108 m/s) Wavelength: the trough to trough distance or the distance from one peak to another. Frequency: the number of ocillations at a certain point per second. Amplitude: relates to the intensity of the light hubblesite. org/reference_desk/faq/answer. php. id=72&cat=light. Where v= frequency, = wavelength and c= speed of light. There is an inverse relationship between wavelength and frequency. Diffraction: the passing of a wave through a narrow slit or bending of a wave around an obstacle. When two or more waves of the same frequency and phase add up to form a single wave. When two waves are not in the same phase they cancel eachother out or form a wave of lower amplitude. The particle like properties of light are explained through the photoelectric effect.
