If our visual sense is giving us information that is in conflict with information from another sense, we tend to bias our trust towards our sense of vision. Our visual sense: the eye is primarily an instrument to collect, focus, and sense the light. Although there is some initial processing done on the information collected, the heavy-duty processing occurs in the brain. Amplitude: amplitude is the height of the wave, variations in amplitude affect the perception of brightness. Generally, 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. (see image below, left. ) Wavelength: distance between the peaks of successive waves, variations in wavelength affect the perception of colour.
