My son has a ceiling fan in his room and one Christmas, while he had blue snowflake lights strung up, we noticed that if we turned the fan on high with the blue lights on, we could see every blade.
Does the color of light effect the speed of the object your eye can see? I would love to know what was going on.
This is almost along the same lines as this post, but we've figured out a way for the eye to not see the blades as transparent:
Thanks in advance
