It was formerly believed that only mass was affected by gravity. When Albert Einstein proposed his Theory of General Relativity, which suggested that gravity was actually a distortion in spacetime, scientists put it to the test during the solar eclipse on May 29, 1919, by measuring to see if the sun's gravity bent the light from distant stars as it passed by -- and found, indeed, that it did.
Now back to black holes: all objects with gravity have a certain escape velocity (the velocity at which an object must move at in order to escape the certain object's gravity's spacetime snare; in other words, the velocity at which you would have to throw an object off the earth in order for it to never fall down) that depends on the ratio of the mass of the object to the square of its radius. If this ratio is sufficiently great enough so that the Universal Law of Gravitation can be rearranged to give a value for escape velocity that is greater than c (the speed of light), then the object with escape velocity > c is a black hole.
When light passes by the event horizon (the radius from a black hole at which the greater-than-c escape velocity takes effect), the light will bend around and around the black hole instead of merely being deflected, as the star's rays were when they passed by the sun during the eclipse. Just as an object thrown off the earth with insufficient velocity falls back down to earth, light falls down into the black hole.
photons
Black as a color would absorb all visible frequencies of light. A "black light" is not actually black, but rather emits most of its light in the ultraviolet frequencies. This light is invisible to our eyes except that it interacts with certain materials that fluoresce (glow in the dark) when they absorb UV light. These lights are also used for indoor plants that need UV light to grow.
Light hits everything, however black objects absorb it.

Black absorbs the most heat. There are special coatings that have been engineered to absorb as much energy as possible 8or economic). Most of these are very dark, blue or black.
Bonds in molecules absorb light, In black the bonds absorb a lot of visible light frequencies. As black only reflects few frequencies of visible light. it gains it black colour.
Black absorbs light more.
Black surfaces absorb all light. White surfaces do not "reflect black" as there's no such thing as black light.

Black
They absorb light which is converted into heat energy
The objects is black when no light reflect from it, hence, it absorb light very well. And at the same time, what can absorb light very well would radiate heat very well .
Black holes.
black
the reason is all light colors for example white, yellow don't absorb light they just reflect it, but dark colors absorb it the light and black being the darkest color absorbs the must heat and light.
Actually, any black object will absorb sunlight - that's why we see it black, because less visible light is reflected.
No. A photon is a particle of light. It is massless.
