What colour will a white object appear if only red light was shone on it?

Red.
The colour of an object is determined by the wavelengths of light it reflects and absorbs, and a white object is one that reflects light across the visible spectrum. If only red light shines on it, it will reflect that light. In contrast, a black object appears black because it doesn't reflect any visible wavelengths, so would still appear black. Any object that doesn't reflect the wavelength of light you're using (eg blue objects) would also appear black because it isn't reflecting any light.

Why do red object's look black in blue light?
Red and blue are primary colours therefore they do not contain any other colour. When a blue light is shone onto a red object, all the blue light is absorbed by the red object, and as no red light is being shone for the red object to reflect, no light will be reflected from it and it will appear to be black. It is important to remember that physical colours will only reflect it's light colour equivalent. All other colours are absorbed. So red will reflect red, green will reflect green, and red will absorb green and so on.
