Question

Why is ‘black’ the absence of light? And because of this, why are we still able to see black print on a paper?

Please help , thank you so much!!

Answer 1

Black is the result of absorbing all colors with different wavelengths. No light is reflecting off it that we can see. So we can see it in white because as far as our eyes, there is just enough contrast in the light against the white for the print to be visible.
