If you shine a green light on a red cap, the cap will likely appear dark or black because red objects absorb green light and do not reflect it back to our eyes. This is due to the color mixing phenomenon where red and green cancel each other out.
To make green appear black, shine red light on it. Green absorbs red light, so when red light is shone on green, the green will appear black.
When you mix red, blue, and green light together, you get white light. This is because red, blue, and green are the primary colors of light, and when they are combined at full intensity, they create white light.
In terms of the light colour spectrum, yes. Red and green light mixed will produce a yellow light. Red and green paint however will create either brown or black.
You get white light, the basic light colour you see every day.
black
To make green appear black, shine red light on it. Green absorbs red light, so when red light is shone on green, the green will appear black.
When green and red light shine on a green leaf, the green light is mostly absorbed by chlorophyll for photosynthesis. The red light is less efficiently absorbed, so some is reflected back, leading to the leaf appearing green to our eyes.
When you mix red and blue, you get magenta. When you shine a green light on magenta, the green light will be absorbed by the magenta, resulting in a dark color or black, depending on the intensity of the green light.
yellow
A red cap may appear black under green disco lights due to the way colors are perceived based on the light's spectrum. The green light primarily stimulates the green receptors in our eyes, while the red pigments in the cap do not reflect green wavelengths effectively. As a result, the red cap absorbs the green light and reflects very little, making it look black or very dark in that lighting condition.
yellow
The green light would be reflected, but the red light would be absorbed. ---Ryan Wang---
I am not exactly sure, but red and green paint together make brown.
When red light and green light shine on red curtains, the red curtains will appear red. This is because objects appear a certain color based on the wavelengths of light they reflect. Red objects reflect red light and absorb other colors, so even when green light is shone on them, they will still primarily reflect red light, maintaining their red appearance.
The white screen will appear yellow because when red light and green light shine on a white surface, they combine to create yellow light. This is because red and green are complementary colors that combine to create yellow.
When green light shines on a green leaf, the leaf absorbs most of the green light and reflects some of it, giving the leaf its green color. Red light is not absorbed as efficiently by the leaf, so it gets reflected, making the leaf appear green under white light.
Things appear red because they absorb all wavelengths of visible light apart from red this will be reflected. If you only shine green light on the object it will all be absorbed and no light will be reflected so it will appear black.
