The author did not understand these and thought them perhaps to be due to changes in reflectance.

Also, the reflectance of the ceiling, walls and floor must be known.

"I bet this surface has a reflectance of greater than a hundred percent."

Its reflectance did not exceed 7.5% of the white card reading in any trial.

Paper reflectance can achieve a dynamic range of about 100:1.

The intensity of reflectance was also slightly less for older males.

Lighter pavements have solar reflectance rates of 25 percent or higher.

Reflectance values for soils and various types of vegetation range from 5 to 45 percent.

In these cases there is surface reflectance and absorption.

The appearance of various materials are determined to a large extent by their reflectance properties.

If a screen material looks grey on casual examination then its total reflectance is much less than 1.

The total diffuse reflectance would be and added together.

Data can be collected in reflectance, transmission, or emission mode.

One, black velvet, was outstanding in all ranges, its reflectance being almost zero.

One possibility is that this measure too responds, at least in part, to the reflectance, rather than merely the area.

This reflectance is so high, that the integrity of data can be kept intact over long distances.

Less than ten percent of beach clasts have reflectance values lying between 50 and 80%.

The blasting media is selected to develop the color and reflectance of the cast surface.

In this area of highly elevated reflectance values no oil and gas occurrences are known.

Yet little is known whether their UV reflectance changes because of age or other factors.

The complex reflectance ratio, , of the system is measured.

Typically, one would like to know the reflectance and transmittance of the layer structure.

A related material property is the reflectivity (also called the "reflectance").

There is a possible problem with specular reflectance when viewing towards the light source.
