Reactor,
You still can not tell me what time of day it is can you?
No, but you have not established why this matters for reflections. In fact, it does not, especially when you understand how Rayleigh scattering works. The point is, you made a statement about needing to know the position of the sun or the general time of day to know where the reflections are, yet you did not substantiate that with any facts of physics to support it. You only
thought that you had one-upped Darby... sorry.
And, what do you mean it is not true for reflections? I would be most interested in what you have to say on this.
The optical physics for shadows and reflections are two completely different phenomena. For one thing, reflection depends upon the
reflection coefficient between the medium that light is traveling through and the medium it is reflecting off of. The physics of
reflections also depends upon refraction. The casting of shadows has nothing to do with any of these optical properties.
The reason why reflections are not sensitive to the position of the sun, especially on earth due to the composition of our atmosphere, relates to how light is scattered by a given propagation medium, and specifically
Rayleigh scattering. Because of Rayleigh scattering, the reflections you see on the photo from the palm trees are not dependent upon the position of the sun. And, as you can read in the last link I provided, Rayleigh scattering is also the explanation for that eternal question asked by most kids "why is the sky blue?"
