Question and answer
Q: what happens when you shine a ray of light at a mirror?
A: The light will be absorbed of course. [ Mirrors aren't that good at reflecting light are they? I would say that a perfect white colour would reflect light better than a mirror. The colours we see is the colours (wavelengths) that is reflected from the material. White light is made up by all colours, and since a mirror also reflect colour and not just white it is a poorer reflector than a
perfect white colour, isn't it??? That doesn't follow. A mirror "also" reflects colors because colored light, not white line was shone on it. A mirror could reflect all the light incident on it and if the light was red, then the light reflected is red. A white surface does not show as much color (but will show some) because the light is "diffused". That is, if you were standing at exactly the "angle of reflection" at a mirror, you would see the red light reflected to you. With a white surface, the red light is reflected in every direction while the light you see would also include white (or other colors) from other parts of the room. -------------------------------------------------------------------------------- ]
