The absorption coefficient of aluminum typically depends on factors such as the thickness of the aluminum and the wavelength of the incident radiation. In general, aluminum has good optical transparency in the visible spectrum but absorbs strongly in the ultraviolet and infrared regions. Its absorption coefficient can vary from near-zero to high values depending on these factors.

What is the value of linear absorption coefficient for Gold?
The linear absorption coefficient for gold depends on the wavelength of the incident light. At a typical visible wavelength of around 550 nm, gold has a linear absorption coefficient of approximately 5.5 x 10^5 cm^-1.
What is absorption coefficients?
Absorption coefficients measure how well a material absorbs energy (such as light, sound, or radiation) at a given frequency. Higher absorption coefficients indicate stronger absorption of the energy by the material. They are commonly used in various scientific fields to understand the interactions between materials and energy.
What is a linear absorption coefficient by using He-Ne laser?
The linear absorption coefficient is a measure of how much a material absorbs light at a specific wavelength. It is typically expressed in units of cm^-1. By using a He-Ne laser, which emits light at a specific wavelength of 632.8 nm, one can measure the absorption of a material at that particular wavelength to determine its linear absorption coefficient.
What is the coefficient of friction between tool steel and aluminum?
The coefficient of friction between tool steel and aluminum typically ranges from 0.4 to 1.05, depending on factors such as surface finish, lubrication, and pressure. It is recommended to consult specific friction tables or conduct experiments to determine the coefficient of friction for a particular combination of materials.
What is the absorption coefficient of concrete for radiation?
The absorption coefficient of concrete for radiation depends on several factors such as the type of radiation (gamma, neutron, etc.), the composition of the concrete, and the energy level of the radiation. Generally, concrete is considered a good shielding material for radiation due to its high density and composition. It typically has absorption coefficients that can range from 0.1 to 10 cm^-1 for gamma radiation.
What is an approximate linear absorption coefficient of steel?
linear absorption coefficientAccording to the results of a laboratory experiment I did, the gamma-ray linear absorption coefficient for aluminum is about 10m^-1, and for lead is about 48m^-1, so considering steel is roughly twice the density of aluminum, I'd guess it would be about 20m^-1, however this experiment is not confirmed.
What is the absorption coefficient of concrete?
Absorption coefficient of concrete for what? For sound waves, mechanical vibrations, radiation, etc... Next question is for what energy? Coefficient if a function of energy rather than a constant.
What is an absorption coefficient?
An absorption coefficient is a measure of the absorption of electromagnetic radiation as it passes through a specific substance - calculated as the fraction of incident radiation absorbed by unit mass or unit thickness.

What is the sound absorption rate of human body?
The rate of sound absorption of an object, surface or body is called the "Absorption Coefficient" which relates to the amount of sound absorbed by the surface. see this chart for details http://www.saecollege.de/reference_material/pages/Coefficient%20Chart.htm
How do you calculate absorption coefficient of water?
water absorption coefficient = 1/a x M/sqrt time a = surface area M = Mass of water absorbed This calculation is relevant to Properties of Masonry Units.
What is the coeffiicient of skin?
Can't answer without more information. Coefficient could refer to the friction, absorption or electrical coefficient, among very many others.
What materials have positive temperature coefficient?
the materials are silver, aluminum, gold.
What is the coefficient of kinetic friction between aluminum and cork?
0.35, approximately
What is the coefficient of kinetic friction between aluminun and felt?
