Obviously the excact same Red.
A "beam" or "ray" of light would best describe the light that shines from a flashlight.
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.
The yellow shirt would appear black because yellow absorbs green light, rather than reflecting it.
black
All other colours except red are absorbed.. The reason it seems red to our eyes is because only red colour is reflected back.
A "white surface" is one that reflects all colors of light. That's why it looks white when a white light shines on it, and that's why you call it "white". If only red light shines on it, then it looks red.
Why do you call that flower a "red" rose ? Could it be because it appears red in typical 'wideband' solar or household light ? That must mean that when light of many colors shines on it, the rose absorbs everything except red, and red is the only light left to bounce off of it toward your eyes. If that's the case, and you illuminate it with light of any single color other than red, then the rose will absorb that light and appear black.
When red light from a laser shines on a prism, it will be refracted (bent) by the prism and split into its component colors (red, orange, yellow, green, blue, indigo, and violet). This is due to each color having a different wavelength and therefore a different angle of refraction when passing through the prism.
If it has light, the flashlight is working.
The plant would never flower, it needs blue light to flower but it would grow normally....
Yes, purple is a color that is a combination of blue and red. When light shines on an object that appears purple, the object absorbs certain wavelengths of light while reflecting others, causing it to appear purple to our eyes.
Correct. No light, no color.
