emissivity's Usage Examples:

The emissivity of the surface of a material is its effectiveness in emitting energy as thermal radiation.

temperature when the body's emissivity curve (as a function of wavelength) is not known.

When the star's or planet's net emissivity in the relevant wavelength.

substance with low emissivity would be silver, with an emissivity coefficient of .

An example of a substance with high emissivity would be asphalt,.

body is the body's emissivity, so that a black body has an emissivity of unity (i.

Absorptivity, reflectivity, and emissivity of all bodies are.

in solar constant or change of albedo or effective earth emissivity.

The average emissivity of the earth is readily estimated from available data.

emissivity—of black-body energy levels.

By definition, a black body in thermal equilibrium has an emissivity ε = 1.

A source with a lower emissivity,.

Low emissivity (low e or low thermal emissivity) refers to a surface condition that emits low levels of radiant thermal (heat) energy.

(high thermal resistance), high emissivity and good thermal stability (refractoriness).

Porous ceramics with high emissivity coatings (HECs) are often employed.

To keep the sun's heat out of the house, a low-emissivity coating should be applied to the outside pane of glazed windows.

By knowing the amount of infrared energy emitted by the object and its emissivity, the object's temperature can often be determined within a certain range.

that problems existed with relying on knowledge of the value of emissivity.

temperature can be described by a dimensionless ratio, sometimes called the emissivity: the ratio of the emissive power of the body to the emissive power of.

The emissivity of a material specifies how well a real body radiates energy as compared with a black body.

This emissivity depends on factors.

the first maps of deformation and global surface composition, thermal emissivity, and gravity field to study the interior structure of the planet.

emits less total energy than a black body and is characterized by an emissivity, ε < 1 {\displaystyle \varepsilon <1} : j ⋆ = ε σ T 4 .

However, lamps using deuterium have a longer life span and an emissivity (intensity) at the far end of their UV range which is three to five times.

calculated by dividing the brightness temperature by the emissivity of the surface.

Since the emissivity is a value between 0 and 1, the real temperature will.

information limited because of the large-scale variability due to the emissivity of sea ice.

Thermal emittance or thermal emissivity ( ε {\displaystyle \varepsilon } ) is the ratio of the radiant emittance of heat of a specific object or surface.
