Detailed explanation-1: -Black is the absence of the visible light spectrum wavelengths. Everything in a dark room appears black because there is no visible light to strike your eye as you gaze at the surrounding objects.
Detailed explanation-2: -We can see an object only when light rays emitted or reflected from the object reaches our eye. In a dark room, no light reaches our eye. Hence, no objects are visible. Outside the room, all objects are visible because light reflected from their surfaces reaches our eyes.
Detailed explanation-3: -The reason for this darkness is that even the reflected light is very quickly absorbed. No surface is perfectly reflective. This means that with every reflection, some of the light is absorbed. After a few reflections, the last remaining bits of light are absorbed.
