# reflectance ─░ngilizce - ─░ngilizce
The ratio of the flux reflected to that incident on a surface
A spectrum consists of a set of reflectance or transmittance values for the wavelengths scanned during a measurement The term "reflectance" is used if the amount of light is measured which is diffusely reflected by the sample This is mainly the case with solid samples
The fraction of the light incident on a surface that is reflected and varies according to the wavelength distribution of the light
Reflectance is the ratio of power reflected to the incident power at a connector junction or other component junction, usually measured in decibels or dB Reflectance is stated as a negative value, e g , -30 dB A connector that has a better reflectance performance would be a -40 dB connector or a value less than -30 dB The term return loss, back reflection and reflectivity are also used synonymously in the industry to describe device reflections, but stated as positive values
The ratio of the reflected flux to the incident flux, or the ratio of reflected light to light falling on the object
The ratio of light reflected from a surface
ratio of the radiant energy reflected by a body to the energy incident on it (approximately the inverse of emissivity)

reflectivity
A surface property that determines the extent to which an object reflects neighboring objects
reflectivity
Property of illuminated objects to reradiate a portion of the incident energy Reflectivity, in general, is larger in the specular direction for smaller surface roughness For side looking radars, backscatter is the observable portion of the energy reflected Backscatter, in general, is increased by greater surface roughness In general, reflectivity is increased for higher conductivity of the scattering surface The relative strength of radar reflectivity is tabulated by sigma, for discrete objects, and by sigma nought for natural terrain surfaces

reflectivity
A measure of the process by which a surface can turn back a portion of incident radiation into the medium through which the radiation approached It also refers to the degree by which precipitation is able to reflect a radar beam
reflectivity
(sol) (meas)  The ability to reflect SOLAR RADIATION, which is possessed to some degree by all materials It is called the ALBEDO in atmospheric references  The ratio of RADIANT ENERGY reflected by a body to that falling upon it F - pouvoir reflecteur S - reflectividad

reflectivity
the ability of a surface to reflect incident energy (e g , light-colored surfaces tend to have greater reflectivity than dark-colored surfaces)
reflectivity
The ratio of the energy carried by a wave after reflection from a surface to its energy before reflection
reflectivity
the ability to reflect beams or rays
reflectivity
the proportion of incident radiation reflected by a surface, expressed as a fraction or percentage
reflectivity
┬Ā The reflectance at the surface of a material so thick that the reflectance does not change with increasing thickness, i e , the intrinsic reflectance of the surface, irrespective of other parameters such as the reflectance of the rear surface ┬Ā Note: ┬Ā The term "reflectivity" is no longer in common use ┬Ā See reflectance
reflectivity
The measure of the efficiency of a radar target in intercepting and returning Electro Magnetic Energy Reflectivity depends upon the size, shape, aspect and dielectric properties at the surface of the target
