Why does a red and green jumper appears to be a red and black jumper under red light?

White light is made up of all of the colors of the spectrum, so the green looks green because the green light is reflected back to your eyes while the other colors are absorbed. Under a red light, the green light is filtered out so there is no green to reflect so it looks black.

Why a green object appears black when viewed through a red filter?
A green object appears black when viewed through a red filter (here a red filter means red light) because green object can only reflect green color and absorb all the other colors so in the red light it will definitely appear black.
Why does a green leaf appear green in daylight and dark in red light?
Green objects reflect all green wavelengths of visible light, so if it is only under red light, it has no colors to reflect and appears black.
What color does a green and orange object reflect?
An object appears a certain color to you because it reflects that color of light and absorbs other colors of light. For example, a white object appears white because it reflects all colors of visible light (red, orange, yellow, green, blue, indigo, violet). A black object appears black because it absorbs all of these colors--and as a result, none of those colors are reflected back to your eyes. Under white light, the object appears yellow-green because it reflects both yellow and green light and absorbs all other colors. (Remember, white light has all colors of visible light in it). If only green light is present, there's only green light for it to reflect--so it will appear green. If you shined yellow light on it only, it would be yellow. If you shined yellow and green light, it would appear yellow-green again. It you shined red and blue light on it, it would appear black, because it absorbs both of those colors.

Why a green cap looks black in blue light?
The cap is called 'green' because it absorbs all other colors of light, leaving only the green light to bounce from it to your eyes. If no green light shines on it, then there's no light to bounce from it to your eyes, and it appears black. If you only shine blue light on it, then there's no green light shining on it.

Why a red and green jumper apperas to be black under a blue light?
Something red absorbs all the colours of light except red (which it reelects to your eye). Something green absorbs all the colours of light except green (which it reelects to your eye). Thus both red and green will absorb blue light and nothing will be reflected to your eye and the absence of reflected light is perceived as black.

What happens when light waves strike a black wall?
The reason the wall appears black is that it absorbs light in the visible spectrum (~400nm to ~700 nm in wavelength); otherwise, the wall is no longer black. A green wall reflects green light (~500 nm) but absorbs all else. ===========================
If you look through a red filter at a sheet of green paper that is in white light what will you see?
The paper appears black. -- The paper is called "green" because it absorbs any light that isn't green, and reflects only green light to the observer. -- The filter is called "red" because it absorbs any light that isn't red, and transmits only red light through to the other side. -- There's no red light shining from the paper into the filter, so there's no light leaving the filter. The paper appears black.
