Document Summary
1/3 of the brain is devoted to processing visual information. When your visual information is in conflict with information from another sense, humans tend to bias their trust towards their sense of. Light travels as a wave and can vary in two respects: the height of each wave (amplitude), and the distance between the peaks of successive waves (wavelength). These two physical characteristics of light translate into our perceptions of brightness and colour. Variations in amplitude affect the perception of brightness. The greater the amplitude of the light wave, the brighter or more intense an object appears to us (more light is being reflected or emitted by that object) Variations in wavelength affect the perception of colour. Measured in nanometers or millionths of a millimeter. Smaller wavelengths refer to light waves with a higher frequency, since there is less distance between successive peaks. Larger wavelengths = light waves with lower frequency.
