I How see through the glass + reflection at same time

  1. Nov 14, 2016 #1
    When its day we can kind of see our reflection a little bit and also see outside, when its night we can fully see our reflection in the glass window.
    Can someone explain quantum mechanics behind it because i think iv read an article long time ago on it but cant find it anymore.

    I don't know what the article you read long ago was, but I do know that you will find the answer to your question in Feynmann's (very layman-friendly) book "QED: The strange theory of light and matter".

    Why do you think this is a quantum effect? The transmission and reflection can be explained in classical optics by the Fresnel equations. The greater visibility of the reflection against a dark background is not a quantum effect either.

    No quantum mechanics needed.

    Why don't you see the stars during the day? I think the reason is similar.

    Yes i am aware of classical physics explanation but i wanted to hear quantum physics side of it.
    Nugatory i really like Feynman so i will read that book.
