Assuming:-

  1. No ElectronTransition ==> Photon passes through the atom. [right?]

    • Longer Version In Words:-
      If a Photon doesn't have enough energy / has more energy than to trigger a ElectronTransition --> Then it isbelieved / usually told to be "Passing Through The Atom".
  2. https://atomic-spectra.net/sp_hires.png

    • In Words:-
      Lots of elements (even METALs) have big chunks in their spectrum which doesn't cause ElectronTransition --> REF:-

The Question:-

What happens after a Photon pass-es through an element without causing any ElectronTransition? What does it really mean to pass through? (Specially when it was a solid/liquid that the photon didn't cause ElectronTransition to? Will that be different from what is taught in High School about a SingleATOM & that it passes through?)

  1. e.g. What about a Cube/Chunk of Scanadium?
    FOR-REF:https://en.wikipedia.org/wiki/Scandium#/media/File:Scandium_sublimed_dendritic_and_1cm3_cube.jpg
  2. What if we shine the Photons on it that doesn't cause ElectronTransition to it?
    Shouldn't Scanadium let those Photons pass-through in straight line & appear Transparent?

Want to watch but feels really hard

Photons pass through glass all the time without causing a transition.

Metals are different. Even though they don't promote a bound electron from one orbital to another, they do interact with photons. Metals contain electrons in states that are not attached to a single atom. These electrons can move within the metal.

In a simple classical description, light is an oscillating electromagnetic field. The field causes electrons to vibrate. The vibration absorbs the incoming light. Accelerated electrons radiate. This is the reflected beam.
