eli5: Does the reflection of light in windows/mirrors also produce light?

366 views

Ever since I was young, I’ve always wondered if reflected light from windows also produces light. I never asked because I thought it was a “dumb” question. Guess this is the right place…

ps: sorry if I made mistakes, I’m not a native speaker 😉

You answered your own question. A reflection doesn’t produce light, it reflects light. There is no energy production in a window for example.

It can still look like a light source though, just like the moon looks like a light source even though it’s just sunlight reflecting.
