It is all down to the physical properties of the material in question. The way bonds are formed the way an electron orbits the spin of those electrons the over all spin etc etc.

Light moves in waves. Transparent things have their molecules arranged in the right way so that these waves of light can fit through them. Something that is transparent for one "wavelength" is not transparent for all wavelengths. For example, the light we see is the right wavelength to "fit" through glass, but "infrared" light can't get through.
Shiny things reflect light because when a photon (a light particle) hits them, it is absorbed and then the shiny thing releases another photon.

Because that is there nature. Go back and read Marcus Aurelius 'On the Nature of Things' for a deeper philosophical perspective. Then pay attention in P-Chem.

different structures and levels of refraction.iron being attracted to magnetism is different,it is one of the mysteries of science,but at least it has positive and negative,unlike gravity which is not understood at all.
