Aluminum can reflect up to 97% of light that falls upon it when highly polished, but how does it do this? Reflections occur when light hitting a material provides enough energy for an electron to move to an excited state, from where it emits a photon of light upon returning to its ground state. In aluminum there are many electrons that are free to easily become "excited" like this, this makes it an extremely good reflector.

what do you know about prime aluminum?
Prime aluminum industry is one of the highest leading aluminum company in Pakistan. Prime aluminum Providing the standard aluminum profiles in Pakistan. We are the top aluminum manufacturers and aluminum suppliers in Pakistan.
What is made out of aluminum ore?
Aluminum is made out of aluminum ore.
Is aluminum oxide metallic?
No, aluminum oxide is not metallic. But aluminum is.
How is pure aluminum different from an alloy of aluminum?
Aluminum alloy has precipitates of alloying elements which improves the mechanical property of aluminum but pure aluminum is weak.
Is Aluminum Sulphate Sulfur?
No. Aluminum sulfate is a compound of aluminum, sulfur, and oxygen.
What are some physical facts about aluminum?
Aluminum is light weight, moldable and weldable. It conducts heat and electricity well. It is reflective.
What type of aluminum foil to use for reflection?
All aluminum reflects light well. Aluminum foil is made from an aluminum alloy which contains between 92 and 99 percent aluminum and therefor should be able to accept a good reflective finish..
What is The reflective coating on the back of a mirror?
The mirror substrate has either a polished silver or aluminum coating to the back .
Which metal has highest reflective index?
i think aluminium, its the most common reflective one anyway. Actually I am in the middle of a project that requires this information. Silver exceeds aluminum. Silver has a 98% RI and Aluminum is 90%.
What elements found in the mirrors?
Most mirrors are a sheet of glass with a highly reflective coating of aluminum on one side
What is a stop sign made of?
An aluminum sheet is first cut into the shape of an octagon. Reflective sheeting is cut into the background sheeting and letters. They are then assembled and placed in a heat lamp to seal the sheeting to the aluminum.
What is in aluminum foil that keeps the heat in absorbs it?
Aluminium foil is reflective and as a result heat and light that hits it is bounced back to where it came from. tinfoil
What is more reflective toward radiation mirror or aluminum foil?
I would have to say aluminum foil, since radiation can travel through glass. radiation is reflected from the surface of aluminum foil. With a mirror the radiation has to travel through a small layer of glass twice before the mirror is finished with it. Glass is not totally transparent, some light is absorbed so the naked aluminum reflects better.
Why does aluminum foil keep stuff hot and cold?
Aluminum foil is air tight. It works by sealing the item from the atmosphere. There is some assistance from the reflective surface, but not much. And it works best if it is not in contact with the item being protected, as it conducts heat very well.
What is mirror made of?
Glass, silver paint (or foil) and black paint. The silver paint or foil reflects the light that hits it, the black paint prevents light from behind washing out the image and helps protect the reflective surface from damage. The glass also helps protect the reflective surface as well as focus the reflective image.AnswerThe elements that make up mirrors are silycon, oxygen, and silver. Modern mirrors are made by vacuum deposition of aluminum onto a smooth base, then covering with glass. The glass makes for a smoother surface and also protects the aluminum from damage. Fundamentally, the plate is placed in a chamber which is then evacuate. Aluminum is vaporized, and condenses on the surface of the plate.Also, aluminum can be vacuum deposited to the glass itself. It is often given a black backing to improve opacity and reflectivity. At one time mercury was used, but no longer due to health an environmental issues.
How can you boost GSM 3G cellular reception?
You can boost a GSM 3G cellular signal by placing the device on a reflective surface like aluminum foil. This will bounce back some of the signal which will boost the signal.
Good materials for a bike mirror?
To make a mirror it has to be reflective. Glass is prone to shattering into dangerous shards, so polished aluminum, metallized plastic or chromed steel would probably work better.
