Final answer:
In physics, black and white are not considered real colors in the same way that red and green are. Colors are perceived based on the wavelengths of light that are reflected or absorbed by an object. So while black and white are common terms used to describe the absence or presence of light, they do not represent specific colors like red and green do.
Step-by-step explanation:
In physics, black and white are not considered real colors in the same way that red and green are.
Colors are perceived based on the wavelengths of light that are reflected or absorbed by an object. Black objects absorb all visible wavelengths of light, while white objects reflect all visible wavelengths of light. Red and green, on the other hand, are specific wavelengths of light that can be seen by our eyes.
So while black and white are common terms used to describe the absence or presence of light, they do not represent specific colors like red and green do.
