Document Summary
When visual information is in conflict with information from another sense, you tend to bias your trust towards your sense of vision for most people, seeing, truly is believing. The eye is primarily an instrument to collect, focus and sense the light stimulus. Light travels as a wave and can vary in two respects: the height of each wave, called the amplitude, and the distance between the peaks of successive waves, called the wavelength. Variations in amplitude affect the perception of brightness. The greater the amplitude of the light wave, the more light is being reflected or emitted by that object, and so that object appears brighter or more intense to us. Variations in wavelength affect the perception of color. Wavelength is measured in nanometers, or millionths of a millimeter. Smaller wavelengths refer to light waves with a higher frequency, because there is less distance between successive peaks. Larger wavelengths refer to light waves with a lower frequently.
