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 else can I help you with?
Is aluminum a lustrous metal?
Yes, aluminum is a lustrous metal, meaning it has a shiny and reflective surface.
What is the appearance of aluminum?
Aluminum is a silver-white, shiny metal. It is lightweight and has a smooth, reflective surface.
What is typically found on the back of a mirror?
A reflective coating, such as silver or aluminum, is typically found on the back of a mirror.
What is aluminums texture?
what is aluminum texture
Why does aluminium lose its shine when exposed to air?
Aluminum forms a thin layer of aluminum oxide when exposed to air, which is dull in appearance and not as reflective as pure aluminum. This oxide layer protects the aluminum from further corrosion, but it also contributes to the loss of shine.
Is aluminum a lustrous metal?
Yes, aluminum is a lustrous metal, meaning it has a shiny and reflective surface.
What is the appearance of aluminum?
Aluminum is a silver-white, shiny metal. It is lightweight and has a smooth, reflective surface.
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 elements found in the mirrors?
Mirrors are typically made of glass with a reflective coating on one side, usually made of silver or aluminum. The reflective coating is what allows the mirror to reflect light and create an image of objects placed in front of it. Additionally, mirrors may have a protective layer of paint or sealant to prevent damage to the reflective coating.
What are the three physical properties of aluminum foil?
Lightweight: aluminum foil is thin and typically weighs around 7.15 grams per square meter. Ductile: it can be easily bent and shaped without breaking. Reflective: it has a high reflective surface that can reflect heat and light.
What is typically found on the back of a mirror?
A reflective coating, such as silver or aluminum, is typically found on the back of a mirror.
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 is The reflective coating on the back of a mirror?
The reflective coating on the back of a mirror is typically made of a thin layer of metal such as aluminum or silver. This coating reflects light that hits the mirror, allowing us to see our reflection.
What is aluminums texture?

What element forms a corrosion proof relective coating on telescope mirrors?
Aluminum is commonly used to form a corrosion-proof reflective coating on telescope mirrors. The aluminum coating is applied through a process called thermal evaporation or sputtering, creating a highly reflective surface that improves the telescope's performance.
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.
