    why silver atoms reflect light? why they don't refract it, like the Huygens's principle says?

    I found out why about a year ago but have since forgot, its something to do with energy levels or something.

    Light reflection is a complex problem.
    Sometimes, we give a simplified answer.
    As Einstein said, any light has their own frequency, and the energy of the light is proportional to the frequency.
    The matters reflect one kind light, such as red, because they do not absorb the frequency of red light and diffuse it.
    Example: the desk is blue. because the desk absorb (or diffuse) most of the color except blue, it reflects bule as you see.

    Metal atoms absorb one kind light before refracting(diffusing) it.
    Why water doesn't absorb but refract it? because water has no free electrons.
    I think you may be confused, But these are the fact before you read "Solid Matter physics"
