Document Summary

Light could be meaningless it depends how you process/interpret it. Experience allows us to interpret and define what the light is. Everything we see is converted by the brain interpreted in different way: what is real how does the brain interpret it to make sense . Approximately 400nm 700nm: only 1/17, 700 = red light to us th of the total spectrum. Qualities of light: hue (colour, brightness (dark/light) Illuminance: amount of light that actually reaches an object to be viewed. Luminance: amount of light reflected off of an object: used in aircraft design, need to be able to see the aircraft. Electromagnetic energy [transformed] into electrochemical neural energy by the eye. Cones: visual receptors that mediate high acuity colour vision in good lighting. Rods: visual receptors that mediate achromatic low acuity vision under dim light: night, b&w. Photopic vision: sufficient light to activate rods & cones: cones are dominant. Differences put great limitations on our visual sensory processing.
