Main Question or Discussion Point
I was watching this video ( ), and around the 1:52 mark the woman said that it is impossible to image molecules with visible light. By her demonstration, I took this to mean that we can't use visible light to image molecules because visible light is too large to be reflected by the molecule. The problem that this raised in my mind is how can electrons reflect light if a molecule, which is much larger than an electron, cant? If anyone has an answer, I would be glad to hear it.
