Is gold a good heat reflector?
Surfaces designed to reflect a broad spectrum of electro-magentic waves, (shiny things generally, like mirrors or polished metal) specifically infrared wavelengths are good reflectors of radiant heat.
Gold is the best material for reflecting radiant heat..
What are good reflectors of heat?
Black surfaces are the best absorbers of heat radiation. Shiny surfaces are the best reflectors of heat radiation. Shiny surfaces are poor absorbers of heat radiation. Glass will not transmit long wave infra red radiation.
Is glass a better sound reflector than concrete?
Glass is considered to be a better sound reflector than concrete, although both the material have low sound absorption critical frequencies.

What absorbs sound the best?
In general, soft, pliable, or porous materials (like cloths) serve as good acoustic insulators – absorbing most sound, whereas dense, hard, impenetrable materials (such as metals) reflect most. How well a room absorbs sound is quantified by the effective absorption area of the walls, also named total absorption area.

What are good and bad reflectors of sound?
Good reflectors means which reflect the sound clearly. Bad reflectors means which do not reflect the sound clearly. Are substances that reflect waves (sound, light, etc.). … Such surfaces cause light to bounce (reflect) at the same angle in which the light hit the object.
What kind of surface is the best reflector of sound?
3 Yes; plywood is a good reflector of sound. It has a very low sound absorption coefficient (0.02). 4 Hang pleated curtains (0.75) in front of the back walls (0.02), (or cover the wall with mineral wool (0.65)). 5 Hard, flat surfaces include steel (0.03), glass (0.03), plaster (0.02).
Is Metal a good reflector of sound?
Answer. are substances that reflect waves (sound, light, etc.). … Such surfaces cause the light waves to scatter. Therefore, substances that could be listed on the “good reflectors” side of your table are: metals (aluminum, copper, silver, gold, spoons, etc) and mirrors.
