Conductor of electricity are compounds that allow electricity to pass through. They are metallic and sometimes ductile and malleable. Very common is iron. The most metallic element is francium.
insulator...as opposed to a conductor which does allow electrons to travel freely within it.
Answer -Examples of Opaque Objects-wood, leather, rubber, iron, gold etc.
Objects that allow most light to pass through are described as transparent. In contrast, translucent objects allow some light to pass through, but don't let you see objects. Opaque objects allow no light to pass through.
Conductors allow electricity to pass through them easily and insulators don't let electricity pass through easily. Some examples of conductors are most metals and some examples of insulators are wood, rubber, and plastic.
Materials that allow energy to flow easily through it are called conductors.
Wood An insulator is a material that does not allow charges to move through it easily.
Sound is a pressure wave. Objects that "allow" sound to travel through them could be called wave guides.

rubber would be an example of something that does not allow electricity to move through it easily

Opaque objects don't allow light to pass through them while translucent objects slow the passage of light but ultimately allow it to pass through.
the substances that allow heat to pass through them easily are called heat conductors. the substances that do not allow heat to pass through them easily are called heat insulators. ruchi
