Because its at the blue end of the light spectrum, visual light is in the middle (what we can see) and infra red is at the other (red end) of the spectrum.
Really?.
Does it appear blue? To whom? Or...
the reason why is that when you look at a color, the light from the sun makes it reflect into your eyes thats how you are able to see black as black. I hope that made sense
Because it absorbs all visible light. Visible white light can be divided into 7 colours (the rainbow). Every object appears as the colour they are because they reflect that colour from the rainbow...
Destructive interference. If the sheet is very thin, near half the wavelength of the incident light then light reflected from the top layer is out of phase with light reflected from the bottom layer....
