Ask an Expert: The eye's response to colored light
2 posts • Page 1 of 1
Do you know why or know the experiment where if you stare at a colored light bulb for a few seconds, then at a white surface, your eye sees dots of the next color on the visible spectrum? For example, stare at a yellow light and you see green dots? Why is that?
There's a decent explanation of the phenomenon in a similar Science Buddies experiment, here: http://www.sciencebuddies.org/mentoring/project_ideas/HumBeh_p008.shtml?from=Home. It depends on what grade you're in, though; the explanation on that page may be too simple or too complicated for you. If it's either, post back and we can clarify.
