Document Summary
Nearly 1/3 of brain devoted to processing visual information. Height of each wave is called amplitude. Distance between the peaks of successive waves i called wavelength. Greater the amplitude of the light wave = more light is being emitted by that object = object appears more bright or intense to us. Measured in nanometers or millionth of a millimeter. Smaller wavelengths refer to light waves with higher frequency between successive peaks. The infrared spectrum is made up of wavelengths longer than humans are able to perceive. Infrared light lower in frequency and longer in wavelength than the light making up the visible spectrum. Larger wavelengths refer to light with a lower frequency. Visible spectrum: the tiny portion humans are sensitive to of the total range of wavelengths of electromagnetic radiation shortest wavelength we can see is around 360 nanometers = violet longest wavelength 750 nanometers = red.
