In fact, many mirrors are actually a film of aluminum deposited
on the back of a sheet of glass. So yes, aluminum foil does reflect
'like a mirror'. The reflectivity of most common aluminum alloys is
in excess of 98%, in both the visible and infrared ranges of light.
It depends on the thickness of aluminium and also depends on the nature of light. If the Aluminium foil is very thin, then the light may transit small extent. But, in general, the visible light gets reflect.
answ2. Heat is not 'attracted' 'repelled' by anything.Polished aluminum foil will, and thus is a thermal insulator.Aluminium metal itself is a good conductor of heat.It will reflect the sunlight and retain the heat.
Yes, aluminum foil is a good reflector of light due to its shiny surface. It can be used to redirect and reflect light in various applications, such as in photography or enhancing the efficiency of solar cookers.
A sidewalk will conduct more heat than foil in sunlight because concrete has a higher thermal conductivity than foil. This means that the sidewalk will absorb more heat and conduct it through its material, while foil will reflect a significant portion of the sunlight.
The significance of aluminum foil emissivity lies in its ability to reflect heat and light effectively. A low emissivity value means that aluminum foil can reflect a high percentage of heat and light, making it a good insulator and useful for various applications such as insulation, cooking, and packaging.

Aluminum foil is better at keeping things colder compared to plastic wrap. This is because aluminum is a better insulator and can reflect heat more effectively than plastic wrap.
When baking cookies, it is recommended to use the shiny side of aluminum foil to help reflect heat and promote even baking.
The significance of aluminum foil emissivity lies in its ability to reflect heat and light effectively. A low emissivity value means that aluminum foil can reflect a high percentage of heat and light, making it a good insulator and useful for various applications such as insulation, cooking, and packaging.
The emissivity of aluminum foil is low, around 0.03. This means it is a good reflector of heat and does not absorb much heat. As a result, aluminum foil is effective at reflecting heat and keeping objects cool.
Aluminum foil is a good conductor of heat, meaning it can transfer heat quickly. When placed on a hot surface or wrapped around food in an oven, aluminum foil can help trap and reflect heat, aiding in the cooking or warming process.
No, aluminum foil reflects more light than transparent glass. Aluminum foil has a high reflective surface that reflects a higher percentage of light compared to glass, which allows more light to pass through.
Aluminum is element. Aluminum foil is made entirely of aluminum.
Aluminum foil is made of Aluminum, which is an element. So yes Aluminum foil is a element
