Why does not white light when falls on objects makes them appear as black or white?

Many objects do appear black or white when light falls on them. If they are black, it means that the object is absorbing all wavelengths of visible light and not reflecting any. If they are white, it means that they are reflecting all wavelengths of visible light and not absorbing any. The color of an object is due to the wavelengths of light that it reflects.

What colour does an object reflect when it appears black?
By definition, black is the absence of light and color. In the real world, all objects with the possible exception of black holes reflect some light, but objects that appear black are absorbing, rather than reflecting, most wavelengths (colors) of visible light.
Why is hotter when wearing a black shirt?
the light attracts to black so it makes it hotter Black objects are black because they absorb all the visible radiation that falls on it. That light is then converted into infrared radiation which is essentially heat. White reflects radiation so you are cooler wearing white.
How do colored objects look under colored lights?
If the light is or contains the colour the object it is striking, then the object will appear to be the colour it originally is. If the light is not or does not contain the colour the object it is striking, then object will appear black. This is because an object will only reflect the light that is the same colour as it, all other light is absorbed. For example: Red, yellow, magenta, and white light will make a red object appear red as they all contain red light. Blue, green and cyan light will make a red object appear black.
Why does red appear red when light falls on it?
It absorbs non-red light and reflects red light.
Why black body absorbs heat?
Objects appear white when they reflect all wavelengths of visible light. Reflection of various wavelengths of light means that they are scattering the light back into the space surrounding the object, rather than absorbing that energy.Objects appear black when they absorb all wavelengths of visible light, thus absorbing that energy (some of which is converted to heat).
Imagine you are on a strange new planet All the lights in this planet is greenAll the objects are blue What color do the objects appear to be?
Since blue objects absorb the green light, the objects appear black.
Why does space appear black?
We can directly observe light sources and objects that reflect light. Since space contains little of either, it mostly appears black.
Does a pure red paper appear black in pure blue light?
it should do objects absorb all light except light of the colour of the object if there is no light of that colour the object appears black

Why is soy sauce black?
Any black thing, including soya sauce, will appear black because it absorbs most of the light that falls on it. So why do "black things" absorb light? Because their surface or their interior is unable to reflect light. (In other words, "because it does". Why do metals appear shiny and metallic? Because they do!) Black things will normally appear black in other light; but other colours may appear black in other lights. For instance, a blue object may appear black in orange light, because orange light has little blue within it for the "blue" object to reflect.
Why do a yellow bus appear yellow?
Colours appear the way they are because of light. Objects such as this bus reflect colours from light..thats why most things apear black in the dark because there is little or no light to reflect off of. Yellow objects reflect yellow while absorbing remaining colours
Why does something green appear black when photographed in red light?
simple red light does not reflect off green objects and most shades of green have no red in them so you see an absences of light ( also know as black)
How do black holes in space get their name?
A black hole is an objects with such strong gravity that not even light can escape them. If observed up close a black hole would appear as a completely black sphere.

Why does lightning hit black objects?
Light hits everything, however black objects absorb it.

What is the best obsevation of refration of light?
The best observation of refraction of light is by observing objects that are in water. By observing objects that are in water, the objects usually appear as if they are not straight.
