Opaque means no light penetration.
There are three possible characteristics to a materials reflectivity, which are all due to the orientation of its molecules: Transparent - light travels through the material Reflective - light is redirected away from the material Opaque - light is absorbed by the material Foil absorbing light means it is opaque because that is the definition of the term.
You must have Mr. Williams.
wood Think of any material that you cannot see through. Steel, Concrete, Granite,... These are opaque: Light does not pass from one side to the other. Examples of materials that are not opaque: Water, Glass, Air [a mixture of gases]
Yes, most objects that are opaque to visible light also stop IR. Water also stops IR.
Yes, aluminum is opaque.
OPAQUE MATERIALS are THOSE MATERIALS WHICH NOT LET SEE THROUGH
Opaque Materials, such as wood or steel, do not transmit light, accept in the case of a few Physicists, today, claiming that they have, in fact, transmitted light rays through different "holes" in different kinds of opaque materials.

Opaque Material That Light Passes Less
most solid materials are opaque because they are dense. things like liquids and gases are more spread out, that is why they aren't opaque.
Furniture that is not constructed of translucent or transparent materials is opaque.
Such materials through which you can see are called transparent materials. As for example-glass. Such materials through which you cannot see are called opaque materials. As for example- wood
No, a lump of coal is opaque and non-white.
Opaque means not allowing light rays to pass through.
An opaque one.
Not all crystalline materials are opaque, for instance diamond and many others. Some crystalline materials are opaque, it's because they absorb white light, which causes a gap (from IR up to UV) in the transmission spectra.
An opaque material has a more dense pattern of molecules. Opaque materials do not allow light to pass through them.
