Absorptance

Index Absorptance

Absorptance of the surface of a material is its effectiveness in absorbing radiant energy. [1]

7 relations: Absorbance, Absorptivity, Kirchhoff's law of thermal radiation, Optical depth, Photolabile protecting group, Solar gain, Thermal radiation.

Absorbance

In chemistry, absorbance or decadic absorbance is the common logarithm of the ratio of incident to transmitted radiant power through a material, and spectral absorbance or spectral decadic absorbance is the common logarithm of the ratio of incident to transmitted spectral radiant power through a material.

Kirchhoff's law of thermal radiation

In heat transfer, Kirchhoff's law of thermal radiation refers to wavelength-specific radiative emission and absorption by a material body in thermodynamic equilibrium, including radiative exchange equilibrium.

Optical depth

In physics, optical depth or optical thickness, is the natural logarithm of the ratio of incident to transmitted radiant power through a material, and spectral optical depth or spectral optical thickness is the natural logarithm of the ratio of incident to transmitted spectral radiant power through a material.

Photolabile protecting group

A photolabile protecting group (PPG; also known as: photoremovable, photosensitive, or photocleavable protecting group) is a chemical modification to a molecule that can be removed with light.

Solar gain

Solar gain (also known as solar heat gain or passive solar gain) refers to the increase in thermal energy of a space, object or structure as it absorbs incident solar radiation.
