Why is gold used as the reflective surface of some solar panels?
Wiki User

A thin layer of gold that is transparent to visible light but reflective to infrared light is used to keep the temperature of the panels down. This is important in space where the atmosphere does not block solar infrared light, but not needed on the surface of earth.

Why aren't bridges made out of gold?
Gold is rare, Gold is heavy, Gold is soft.
What was the advantage of using hydraulic mining when mining for gold?
Hydraulic mining blasts away the surface of the mine with highly pressurized jets of water. This allows for easy access to the minerals underneath. A negative consequence of Hydraulic mining is the damage to the surrounding environment.
What is gold layered?
Gold Layered is primarily an electrical process. First a piece of base metal, normally brass, is submerged in a plating solution and then an electric current is passed through both the solution and the item being plated. There are many different solutions depending on the amount and color of gold to be plated. This process moves individual atoms of gold out of the solution and onto the item being plated. The gold plate is thus evenly deposited only a few molecules thick over the entire object. Depending on various factors, this coating can be worn away in a very short time or last quite a while. Please do not consider plating as a hobby as the process is much more complicated than this simple description makes it seem and the solutions involved contain highly corrosive acids and deadly chemicals like hydrochloric acid and cyanide. Gold Filled is a abbreviated g.f. = Lower in gold content than 10 KT, usually 1/20 or 1/12 KT. In this technique a sheet of gold is mechanically applied to the surface. Victorian pieces are likely to be unmarked, but later pieces are marked with the fineness of the gold layer, and the part by weight of the gold. For example any piece marked "1/10 12K G.F." is composed of at least 1/10 12K gold based on the weight of the finished piece. In the U.S. gold - filled pieces must be at least 1/20 by weight to be classified as gold-filled.

it stands for GOLD GOLD BOY SUCKS
Why isn't gold used for building structures?
Because Gold is too expensive or Gold isn't very strong. (MPa)

What is the gold wrap on the bottom half of the Apollo landers?
It is a reflective plastic wrap. Mylar plastic coated with gold was used to reflect solar radiation that would otherwise overheat the spacecraft body. Gold-mylar film reflects both visible and infrared radiation.
When was solar panels discovered?
According to Encyclopedia Britannica the first genuine solar cell was built around 1883 by Charles Fritts, who used junctions formed by coating selenium (a semiconductor) with an extremely thin layer of gold.
Why are gold and silver used for coating mirrors?
They are highly reflective.

What is gold's luster?
Yellow, shiny. I don't believe there is a numerical luster scale, just on ordinal one. gold can be polished to as good a reflective surface as any other metal (but some wavelengths will be absorbed thus its yellow color)
What is the difference between circulated and uncirculated American Eagle gold coin?
The American Eagle Gold coins are made in Uncirculated and Proof versions. Circulated means exactly that, it has been circulated and or used. We do not use any gold coins at all in every day business. Proof coins have a highly reflective, mirror-like surface. The surface of a uncirculated coin does not.
Why did the Apollo astronauts who actually walked on the Lunar surface have visors plated with gold while the other astronauts did not?
The Apollo astronauts who walked on the lunar surface had visors plated with gold while the other astronauts did not because they wanted to collect the solar particles.
What do you call gold that you find on the surface?
Gold found on the surface is called alluvial gold.
What kind of plastic is used in making a compact disc?
CDs are made from almost-pure polycarbonate plastic. A thin layer of aluminum or sometimes gold is applied to the surface to make it reflective. This in turn is protected by a lacquer film.
What is the CD made of?
A Compact Disc is made from a 1.2 mm thick disc of almost pure polycarbonate plastic and weighs approximately 16 grams. A thin layer of aluminum or, more rarely, gold is applied to the surface to make it reflective, and is protected by a film of lacquer. The lacquer is normally spin coated directly on top of the reflective layer. On top of that surface, the label print is applied.
Why gold foil is used in?
It is very malleable, doesn't corrode, and has certain desirable reflective qualities.
