Answer 1

solution-;

• Black is the absence of all light. Things appear black when they do not reflect or emit light. White is the presence of all colors of visible light. Objects appear white when they reflect or emit all wavelengths of visible light (or at least three wavelengths - Red, Blue and Green - in equal intensity).

Yes, you must know this one! It forms the basis of most of our logic and reasoning about color, light and the appearance of objects.
