They are called opaque materials.
Opaque materials do not allow light to pass through them. Some examples of opaque materials include wood, metal, paper, and cardboard. These materials block light from penetrating through them, resulting in the inability to see through them.
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.
Furniture that is not constructed of translucent or transparent materials is opaque.
Opaque Material That Light Passes Less
No, opaque materials do not allow light to pass through them, so they absorb or scatter light rather than reflecting it. Materials like wood, metal, and plastic are examples of opaque materials.
Mercury is opaque, which means it does not allow light to pass through it. It has a shiny, reflective surface which is characteristic of opaque materials.
Materials that block light are commonly referred to as opaque materials. This means that they do not allow light to pass through them, resulting in a shadow being cast on the surface opposite to the light source. Materials such as metals, wood, and certain plastics are examples of opaque materials.
No, a lump of coal is opaque and non-white.
