Black
BLACK because the apple absorbs the blue light and there would be no light to reflect.
In an absolutely dark room, a red apple would appear black or indistinguishable from its surroundings since no light is present to reflect off its surface and allow us to perceive its color.
it would appear black because no red light strikes it
A lemon would appear green under green light because the object reflects the color of light that it does not absorb. In this case, a lemon's yellow color would absorb all other colors except green, which it would reflect.
Your eye would perceive the light as yellow because each color corresponds to a specific wavelength of light that is detected by different color receptors in your eyes.
BLACK because the apple absorbs the blue light and there would be no light to reflect.
A purely green apple would look black under purely red light. If the apple were not purely green, it would look dark red. If the light were not purely red, the apple would look dark green. This is because red light does not reflect off purely green objects, and it is the reflected light which we see.
in blue light a apple is black !
Since the apple is green, it would absorb any light that is not the same color as the apple. In this instance, the apple would appear very dark or even black since there is no green in the red light you are shining on the apple. A popular science experiment involves a shoe box, a piece of colored plastic or glass, a few objects (such as the apple), and a flashlight. If a red apple is being used with a red filter, the apple would appear to be a bright red since the apple is also red. The red filter allows the red color being reflected off the apple to pass through. Switch the filter to a green one, and the apple appears black since the filter effectively filters out all colors except green.
the same color it is in the light. objects appear the color that they are because they absorb all colors of light except the one that it appears as. it relects that color and your brain sees it as that. thus, if you have a red apple and a green light on it, it would appear to be black or just really dark. because there is no red light for it to reflect and it merely absorbs the green light. so an apple is the same color no matter what. its just the diffrent affects of light that make it seem different colors.
A banana under a red light would simply be a banana illuminated by the red light. The color of the light would not change the nature of the banana itself.
black
Green
I would personally suggest a light yellow color or white, neither would show through.
it would be a lighter shade of red...!
In red light, a green apple would appear dark or black because red light contains wavelengths that are opposite to green on the color spectrum. This causes green objects to absorb the red light and reflect very little, resulting in a dark appearance.
The blue sky would appear green under green light because the green light would dominate the color seen by our eyes. The color of the sky is determined by the light that is reflected off of it, so when green light is shone on a blue sky, the green light will be the dominant color that is reflected.
