Simple. a mirror
To make a red object look black is when you hold turn off the lights and hold a black light towards it.
The periscope has a reflector to make the light turn corners
The object will appear to be blue. However, the object would be indistinguishable from an object that reflects all colors of light. If yellow light were shone on an object that reflects only blue wavelengths, the object would appear to be black.
the part the red light touches will turn red...like if u get a red laser pointer and point it at a white paper.
According to Blackbody radiation, the darker the object the more light it will absorb. A perfect example is a radiometer, in a light bulb container, there is a thin pin pointing upwards in the middle of the bulb. Then, a little tube with the pin through it has four surfaces. Each surface has a white side and a dark side. If you put something that radiates heat, then it will spin. Since, one side absorb more radiation then the other side, on side is more denser. As a result, it spins.
you hold it and turn it round or if you are physic you can use your physic powers.

turn the light on
Go up the lighthouse and touch the light the lobster will grip the light and turn it right round
a light switch
Believe it or not, the object will appear black! Here's why. An object is red because it absorbs all wavelengths of light except red. It reflects the red back to our eyes, so that's what color we perceive. If you, then, have no other light source and shine purely blue light on a red object, the object will absorb the blue light and you won't get any light reflected at all. In other words, black.
At a red light.
When you mix pink/red and blue, you get purple.
Yes, a school bus can make a right turn on a red light in Pennsylvania.
simple. a mirror. it reflects the light of it
