A green apple appears green under white light because its surface absorbs all colors of light except green. Green light is reflected off the apple's surface and then detected by our eyes, making it appear green.
Under a red light, a lime would appear dark and almost black, as red light does not provide the necessary spectrum to reflect the green color of the lime. The lime's surface would absorb most of the red light, resulting in a lack of color perception.
Laundry detergents often contain optical brighteners that fluoresce under ultraviolet light, such as a black light. These brighteners absorb UV light and re-emit it as visible blue light, making white clothes appear brighter and whiter. This is why laundry detergent may appear to glow under a black light.
Bleach typically glows a yellow-green color under a black light due to the chemicals present in it that fluoresce under ultraviolet light.
Semen may appear fluorescent white or light yellow under a black light on a panty liner. The proteins in semen can react under ultraviolet light, causing it to fluoresce.
Under magenta light, red would appear darker and more muted due to the presence of magenta light wavelengths. The red may also appear more purple or pink depending on the intensity of the magenta light.
When a green apple appears black under a red light, it is because the red light does not contain wavelengths that correspond to the green color of the apple. The red light is absorbed by the apple, causing it to appear black as there is no green light being reflected off the surface to be perceived by our eyes. Each color of light corresponds to a specific wavelength, and when the light's wavelength does not match the object's color, the object will appear different.
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.
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 grass would appear black under orange lights because green objects appear black under light that does not include green wavelengths. Orange lights contain little to no green light, causing green objects like grass to absorb most of the light and appear as black.
It would appear black because the object would not reflect any of the colors of light back.
A white shirt will appear green under a green disco light because objects reflect the light projected onto them. Since the shirt is white, it will reflect the green light predominantly, giving it a green appearance.
Green would appear black or very dark under magenta light because magenta light contains no green wavelengths to reflect back. Therefore, without green light to reflect, green objects would not be visible and would appear dark or black.
Yes, but it is not nesicarally green rock that glows under black light. Some rock are florescent and glow (under black light). Most of these rocks appear green, but not nesicarally all of them.
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.
turquoise(or turquiose)
The red tulip would appear darker, almost black, under the green light due to the color absorption properties. The green leaves would appear bright and vivid as they reflect the green light. The contrast between the red tulip and green leaves would be enhanced under the green light.
Green objects under a green light would appear brighter and more vibrant as the green light would enhance the color by adding more green wavelengths to what is already there. The objects would likely blend in with the background if the light is the same shade of green.
