Why Do Mirrors Look Silver But Reflect All Colors? feynman's Mind-Blowing Answer

Описание: You've looked in a mirror thousands of times. Perfect colors—red stays red, blue stays blue. But look at the mirror itself. What color is it? Silver. That cold, metallic grey.

How does something silver reflect all colors perfectly? When you wear tinted sunglasses, everything looks tinted. So why doesn't a silver mirror make you look silver?

Here's the twist: silver isn't even a wavelength. Look at a rainbow—red, orange, yellow, green, blue, violet. Where's silver? It's not there.

The answer lies in free electrons. When light hits metal, electrons oscillate at the exact same frequency as the incoming light and re-emit it right back. No absorption, no selectivity. Silver isn't a color—it's the visual signature of perfect non-selectivity.
