Because white light is made up of all the colors of the spectrum, and an object that appears red in color is simply reflecting the color red, a white object refects all the colors of the spectrum while black objects reflect no colors at all.

Why does the spectrum appear when White light is shone into a prism?
because the prism splits the white light into all colors of visible light
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.
When white light is reflected . what color will the object appear?
white

What happens when a ray shone at a glass block?
The white light splits into a spectrum.the original colors will appear. This is referred as REFRACTION.
What colour will an object appear to be under white light if it reflects all the colours of light?
White.
What color will an object under white light appear to be if it reflects all the colors of light?
White.
Why do object appear white?
A white object emits light in all/most of the visible spectrum evenly.Because it reflects all the light back.
What would a white object appear under a red light?
Pink.
What kind of pattern of light would you get if you shone monochromatic light on a diffraction grating?
If you shone monochromatic light on a diffraction grating it would alternate bright and dark bands. Only white light white light shone through a diffraction grating would produce a band of colors.
What colour will an object appear to be under white light if it absorbs all the colours of light?
it will be black
