3M (a registered trademark of 3M Company) reflective material enhances visibility during low light hours.
Amount of light reflected back by the surface upon which the bar code is printed.
Property of illuminated objects to reradiate a portion of the incident energy.
Ratio of the radiant energy reflected by an object to that incident on it. Reflectivity is described as a function of radiation wavelength and is determined by the physical composition of the object.
Ability of a surface to reflect light and other electromagnetic radiation. Aluminum has high reflectivity: 80% or more for visible light, and 90% or more for infrared radiation.
the fraction of radiant energy that is reflected from a surface
the ability to reflect beams or rays
the fraction of light that is reflected, rather than absorbed - is an important property of a planet's surface. Reflectivity factors into surface temperatures; high reflectivity (such as white) means little absorption of sunlight and a cooler surface, similar to the advantages of wearing white clothes in summer. Conversely, a very dark surface absorbs lots of sunlight and warms up.
the ability of a surface to reflect incident energy (e.g., light-colored surfaces tend to have greater reflectivity than dark-colored surfaces)
The fraction of solar energy reflected from a surface (as compared to the fraction that is absorbed by the surface). See also "albedo."
The ratio of the total amount of radiation reflected from the object to the total amount of incident radiation.
In the Attributes list, there is Reflectivity to Light, which determines how shiny the object is in general. And there is also Environmental Reflectivity, which affects how well a Reflection Map texture works on the object.
A term to indicate the percentage of reflected light from a painted surface. Considered a function of color rather than specular gloss. Reflectance percentages usually range from 80% to 90% for white colors to 5% to 15% for dark colors. Reflectivity standards vary for each industry and specific application.
See LIGHT REFLECTANCE.
A fundamental property of a material that has a reflective surface and is sufficiently thick to be opaque. One may further qualify it as spectral reflectivity.
Same as albedo. Expressed as the percent of visible radiation reflected from a surface.
A metal's ability to reflect heat, radar and radio waves. Aluminum is a good reflector, and thus is used in radio antennae.
It is a dimensionless value that measures how much incident radiation would be reflected from a surface.
The ratio of the energy carried by a wave that is reflected from a surface to the energy of a wave incident on the surface.
Ratio of incident light to reflected light measured at normal incidence on disk at a specified wavelength
The radar operator uses this radar product to determine the strength or the intensity of a precipitation target. In order for the radar to calculate the reflectivity, it sends out a small burst of energy. This energy strikes the small water particles located in the precipitation target. For simplification sake, it is assumed that these water particles are evenly spread throughout the precipitation target. The more of these particles located in the precipitation target, the greater the return of energy returned back to the radar. One will see a greater reflectivity return from heavy rain than light rain. Reflectivity is expressed in the units of dBZ where dB stands for decibels and the Z stands for reflectivity. See dBZ and VIP.
The measure of the reflective quality of a surface; the relative ability of a given surface to reflect light away from it without absorbing, diffusing or otherwise compromising the light's quality, intensity and spectrum.
radar term referring to the ability of a radar target to return energy; used to derive echo intensity and to estimate precipitation intensity and rainfall rates
The amount of light or energy that bounces off a surface relative to the amount of light or energy that reached the surface. A mirror is an example of an object with high reflectivity. The ocean has low reflectivity. Reflectivity may also be called albedo.
Ability of paper or board to reflect light; a measure of gloss
the capability of a body to reflect the radiation it receives. It is measured as the ratio between the intensity of the reflected light and that of the received light, and its values range between 0 and 1. It is also called "reflecting power" or "albedo"
The ratio of the energy carried by a wave after reflection from a surface to its energy before reflection.
the ability of the surface of a material to reflect the infra red energy of a light source.
A measure of the efficiency of any material surface as a reflector of light, as compared to a Kodak white test card, which is arbitrarily rated at 90% reflectivity. Relative reflectivity is of great importance in photoelectric proximity modes (diffuse, divergent, convergent, fixed-field and adjustable-field), where the more reflective an object is, the easier it is to sense. Download a handy reference on the reflectivity of some common objects.
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.
In optics, reflectivity is the reflectance (the ratio of reflected power to incident power, generally expressed in decibels or percentage) 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. The concept is of some importance in telecommunications and in radars.
