coefficientNumber part in front of an algebraic term, signifying multiplication. For example, in the expression 4x2 + 2xy − x, the coefficient of x2 is 4 (because 4x2 means 4 × x2), that of xy is 2, and that of x is −1 (because −1 × x = −x). In general algebraic expressions, coefficients are represented by letters that may stand for numbers; for example, in the equation ax2 + bx + c = 0, a, b, and c are coefficients, which can take any number. |

| Absorbance is reported as absorption coefficient, which
is comparable with mass concentration per air volume. The comparison requires a
correction for differences in the molar absorption coefficient of
soluble and immobilized fluorescein. Like the MQ Garnet, it measures thicknesses,
refractive indices and absorption coefficients of transparent films from
0 nm to 30 microns thick. |
