Document Summary

Colour: the sensation we het from the quality of light at different wavelength. All light sources give off the same spectrum of light. That is why images taken under totally different light conditions come out looking the same. False ex sun light wavelength is pretty constant, fluorescent light has different picks at different times, same for led. The fact that tungsten light emits much less blue light than sunlight means that it"s difficult to perceive blue colour under tungsten illumination. False the result of the colour perceived is the light source with the material. What ratio of light at different wavelengths make it to your eye. Which of the following is an object with only specular reflection an no body reflection. Mirror we perceive object of different colour bcause they absorbed a certain amount of colour wave if i see red, its because it absorbed moste of the rest of the colored wavelength.
