Gold is exactly as good a reflector as gold. Because it is the same thing.
Yes..
Gold is a really good conductor. Technically, because gold is an excellent reflector of infra-red it can be used as thermal insulation.
White is a good reflector of heat therefore it will absorb less heat than a dark surface.
heat absober absorbs heat & refelector reflect it
Gold is exactly as good a reflector as gold. Because it is the same thing.
yes lead (Pb) is an excellent reflector of heat and is used widely
For example aluminium.
A mirror.
Yes..
Gold is the best heat conductor in the world.
The best reflector for sound will be massive, rigid, and with a smooth surface.
good reflector of heat
Common sense. Is something is reflected, it cannot be absorbed, and vice versa. If something is a good absorber of heat, it tries to "hold onto" as much heat as possible; if something is a poor reflector of heat, it is bad at minimizing heat absorption.
Usually mirrors or a large reflector traps the sun's heat and focuses it on the food.
Silver, copper, gold are the best conductors of heat. In this order.
Gold is a really good conductor. Technically, because gold is an excellent reflector of infra-red it can be used as thermal insulation.
