To understand the concept of black, we first need to grasp the idea of total darkness. This is a state where there's no light source at all, not even a sliver peeping through a door crack. In such a situation, your eyes will adjust to the darkness, but in a completely dark room, you see nothing. This absence of light is what our brain interprets as black.
A simple physics demo can help illustrate this concept. Consider a box with a tube going into it and a door on the top. When you look into the tube, the inside of the box appears black. But when the top door is opened, allowing light in, the walls are revealed to be white. This shows that black is not a color in itself, but the absence of light.
Light is an electromagnetic wave that can span a range of wavelengths, from long radio waves to short gamma rays. The human eye can only see a small portion of this range, known as visible light. Different wavelengths of the visible spectrum are interpreted as different colors by our brains. Interestingly, colors like brown, magenta, or cyan that aren't represented by a single wavelength can still be perceived by our eyes through the mixing of red, green, and blue wavelengths in varying intensities.
Black is not a color in itself, but the absence of light. When there's no light going into your eye, your brain interprets that as the color black.
