Some minerals can exhibit fluorescence when exposed to ultraviolet light (black light). This is due to the presence of impurities or certain atomic structures in the minerals that react to UV light by emitting visible light. The fluorescence can vary in color depending on the mineral and the specific impurities present.

What color would a black ball look In red light?
A black ball would appear black in red light because black objects absorb all colors of light and do not reflect any. Therefore, in red light, the black ball will not reflect any light and will appear black.
How can light make a red object look black?
When a red object is illuminated by red light, it can absorb all the red wavelengths and appear black, as there is no red light to reflect and the object appears dark. This phenomenon is called color subtraction.
What happens when you look at a blue object through a red filter?
When you look at a blue object through a red filter, the object will appear darker and possibly black because the red filter blocks out most of the blue light. The red filter only allows red light to pass through, which results in absorbed blue light and altered color perception.
What color light will make a red sheet of paper look black?
A cyan light will make a red sheet of paper look black because red and cyan are complementary colors. When red light is absorbed by the red paper, cyan light will cancel out the red and make the paper appear black.
What is the wavelenth of black color?
Black is not actually a colour associated with a unique wavelength of light. Black objects absorb nearly all the light at wavelengths our eyes can detect. When we look at something black we are actually seeing 'no light' (or very little compared to the surroundings).White light is the exact opposite; white objects hardly absorb any light. When we look at white objects, our eyes take in light at all wavelengths and we interpret this as the 'colour' white.Visible light wavelength range: 390 to 750 nm (there are 1,000,000 nm in 1 mm)Any light outside this range cannot be seen by humans and could be called 'black'
What happens when hits a black surface?
im assuming that u meant "what happens when LIGHT hits a black surface?" the reason for this is that the black surface ABSORBS the light, and so none of the light waves can be reflected back (which is what makes it look black)
What will happens if all primary color of light are abdorb?
If all the primary colors are absorbed, the surface will look black. It may still be transmitting or reflecting other forms of light (infrared, ultraviolet, and so on) but it will look black to the human eye.
Why does a red book look black in blue light?
because the light is so bright it makes it look black
Why does black look black?

How do the blue bag look if it did not reflect light?
black
What does magenta look like in green light?
black
What color would a black ball look In red light?
A black ball would appear black in red light because black objects absorb all colors of light and do not reflect any. Therefore, in red light, the black ball will not reflect any light and will appear black.
Why the color of darkness is black when no light is there to form a color?
Black is just a "color" made by a surface chemical absorbing all light, therefore meaning that if there is no light, objects will look black.
What color sofa would match with light cherry and black?
