Mercury is liquid, not crystalline, and is reflective. Diamond is crystalline and transparent. Delocalised electrons cause reflectivity, and this has nothing to do with crystalline structure.

The law of reflection states that: angle of incidence i = angle of reflection r. For example, if a light ray hits a surface with an angle of incidence of 45°, it will be reflected with an angle ...

1. The reflection of light from the surfaces of many kinds of leaves has been measured by means of a direct reading spectrophotometer, the measurements being made normal (that is, at an angle of 90⚬ ...

But if you leave it as it is, the light takes 2.37 seconds with an angle of incidence of 16.699° and reflection of 67.380°. Of course, I don't want to manually change the reflection point on the ...

Seeing no reflection: Two pieces of aluminum nitride, a semiconducting material that can be used in light-emitting devices, reflect different amounts of light. The piece at the top reflects 12 ...
