Good conductors like metals are good reflectors of light because they have a high density of free electrons that can easily move in response to an incoming electromagnetic wave, which allows them to re-emit the light waves efficiently. This mobility of electrons causes the incoming light to be reflected rather than absorbed, resulting in high reflectivity.
Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
No, black or dull surfaces are not good reflectors because they absorb light rather than reflecting it. Reflectivity is higher in surfaces that are smooth and shiny, such as mirrors or metals.
Good conductors are called materials that allow electric current to flow through them easily due to the mobility of their electrons. Some examples of good conductors include metals like copper, silver, and gold.
No, high density materials are not necessarily good electric conductors. Electrical conductivity is determined by the availability of free electrons in a material, not its density. Typically, metals with high electron mobility, such as copper and aluminum, are good conductors of electricity.
Good conductors have low resistance. A low resistance allows for the easy flow of electric current through the material. Materials like metals are good conductors because they have many free electrons that can move easily in response to an electric field.
the moon , frosted glass, aluminium
it's reflectors.....

No but they are very good reflectors.
good conductors are better emitters
Metals are good conductors of electricity, two of the best conductors are silver and copper.
Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
metals
Metals, in general. Copper and silver are particularly good conductors.
All metals are solids and good conductors apart from Mercury which is a liquid but is a good conductor.
No, black or dull surfaces are not good reflectors because they absorb light rather than reflecting it. Reflectivity is higher in surfaces that are smooth and shiny, such as mirrors or metals.
They aren't necessarily good conductors of both (like diamond, which is a good conductor of heat, but not electricity) Graphite is one that is both, but most of them are metals.
