Hey, it's me again.
I only recently started to see what Briggsy (a member of this forum, and creator of www.huevaluechroma.com) meant, when he said, that specular reflection is not just determined by the smoothness of a surface.
It's as clear as day to me now, when I think of how different smooth surfaces may have a "clean" (sharp) contoured specular reflection of environment objects in common, which indeed depends on surface smoothness, BUT how the strength of the light reflected is in fact different among them. The amount of light reflected. Although the specular reflection of objects around the surface are all reflected cleanly and clearly, the amount of light, the strength of light is less.
If for example we look at glass, compared to a mirror.
Then I looked at a picture of a sea reflecting the scenery behind it. And it looked as if the reflection was almost as strong as in a mirror in fact. I barely saw any difference between the colors of the actual scenery, and the colors of the scenery reflected on the sea's surface.
Now this confused me. I tried to find what exactly is different between water and glass. And I found that in fact glass has a loose, or more chaotic molecule structure, just like water. Just rigid in place. And that the reason glass for example is transparent, is because the photons of the visible wavelengths of light aren't strong enough (don't contain enough energy) to actually move the neutrons of glass atoms to a higher energy level.
And according to the energy band theory, there are gaps between energy levels of neutrons. Meaning that if the energy of the photons is not sufficient to increase the energy level of the neutrons, to interact with them, they will just pass through.
EDIT: "I also noticed that the specular reflection on a black piano (standing right next to me) almost appears to be mirror like, just that perhaps the mix of the black color of the piano in its' diffuse reflection with the specular reflection decieve my eyes and make the specular reflection appear weaker. As if they share the space of the surface, just one more than the other.
Now when I think about it, Briggsy said, that specular and diffuse reflection are simulataneous processes, of course we know that. But did You mean also on an atomic level? As in, the neutron of an atom absorbs the energy of a single photon (for example) and splits the energy it absorbs and the one it gives back out again? So the energy would be split between what is sent out in specular reflection and what is absorbed and sent out? I feel like I am missing something here."
So what exactly is the difference between water, a mirror (which essentially uses metal coating), and glass?
How is the strength of specular reflection found, or determined?
(not just for these, but in general)
Thanks for Your time. =)
