because when you look at a black object, little light reflects back to your eyes
When light of all colors (wavelengths) is absorbed by an object, the object appears black.
When all colors are absorbed by an object, the object appears black. This is because no light is reflected back to our eyes, resulting in the absence of color and a perception of blackness.
An object that appears black reflects very little light, absorbing most of the colors in the visible spectrum. This means that the object does not reflect specific colors, but rather absorbs them all, giving it a black appearance.
absorbed, which is why the object appears black. The object does not reflect any colors back to our eyes.
Blue what ? ! ? Do you mean an object that appears blue in white light ? Such an object appears black in green light.
An object that absorbs all light appears black, as it does not reflect any light to our eyes.
An object appears black because it absorbs all the colors of the visible spectrum. If we idealize the object to make it perfectly absorptive, it absorbs all of the white light that strikes it and reflects none. In the real world, some light is always reflected. If the object appears black or dark gray, then it reflects small amounts of all colors of the spectrum.
The black object absorbs most of the light energy and converts it into heat, which is why black objects feel warmer in sunlight. The object also reflects some light, but because it absorbs most of the light across all visible wavelengths, it appears black to our eyes.
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.
When white light strikes a black object, the object absorbs most of the light and reflects very little, which is why the object appears black. This is because black objects absorb most of the light across the visible spectrum.
A green object appears black when viewed through a red filter (here a red filter means red light) because green object can only reflect green color and absorb all the other colors so in the red light it will definitely appear black.
