Any black object or surface.
Absorbs all different wavelengths of visible white light, therefore no frequencies are reflected - we detect the absence of frequencies as black!
It absorbs all light frequencies. 
it absorbs all light frequencies
white light
A mixture of all the visible frequencies.
A 'red' apple does not emit red light. Rather, it simply absorbs all the frequencies of visible light shining on it except for a group of frequencies that is perceived as red, which are reflected. This is wrong an apple looks red to us because it reflects infrared waves.
Black absorbs all colors. When visible light hits an object, the object absorbs some colors and reflects others. In the case of black objects, they absorb all colors of visible light, which is why they appear black.
white
White does not absorb light - it reflects all visible light waves, while black absorbs all visible light and reflects nothing.
Anything that absorbs all the visible light that strikes it appears totally black.
White light is what we see when light of all (or most) of the frequencies in the visible spectrum are emitted together from the same source. It is the combination of every visible light wave.
In the visible spectrum of light, all colors have difference frequencies of wave lengths. So, an object that is green would absorb all the frequencies of light with in the spectrum except green, the light reflected from the object then hits our retina and then our brain tells us to interpret that object to be green. The frequencies that are absorbed in to the object are then converted into energy. That's why when you wear black cloths, black absorbs all visible light, you feel warmer, because the light it absorbs is converted into heat. And white would the opposite from that. If you are wondering why they would reflect that certain color, it is because all atoms and molecules have electrons. Electrons in atoms have a natural frequency that they vibrate when light hits them. The light with the same frequency as the natural frequency of the electrons in the atoms would be reflected.
