It will look red. White light is made up of a spectrum of many colours. The primary colours are red, green and blue. An object (in white light) appears yellow because it reflects red and green light but absorbs blue light. In red light, the same object will simply reflect the red light. Since there is no green light, the object will appear red. (A mixture of red and green gives yellow)
It will look black, or green, depending on the hue of the red. A green filter blocks the red light but no red object is reflecting solely in the red wavelengths, and any non-red light will appear green through the filter.
The object would be black, because red cannot reflect green light so no colour is reflected of the object.
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.
Well, the grapes, if in a black room, will absorb off any colours that are not its colour. So the answer would be black. The green grapes would turn black if a red light was shone upon them. ^ hope i have helped!

A green object would look blaack in a red light because coloured objects absorb all colours except the colour they are, so a green object absorbs 6 colours (red, orange, yellow, blue, indigo, violet) and reflects 1 (green). In this situation, there is no green light to reflect and it can't reflect other colours, so it looks black. :)

An object that reflects green and red light would be some shade of yellow or orange, depending on the proportions.
It would be black becasue the object would absorb all the red light, and there would be no green light for it to reflect
i know mate and stop using this its bad
An object that reflects red light and absorbs GREEN COLOUR.
