frequency
reciprocal length









































reciprocal length or inverse length is a measurement used in several branches of science and mathematics. as the reciprocal of length, common units used for this measurement include the reciprocal metre or inverse metre (symbol: m), the reciprocal centimetre or inverse centimetre (symbol: cm), and, in optics, the dioptre.









































quantities measured in reciprocal length include:









































bullet::::- absorption coefficient or attenuation coefficient, in materials science









































bullet::::- curvature of a line, in mathematics









































bullet::::- gain, in laser physics









































bullet::::- magnitude of vectors in reciprocal space, in crystallography









































bullet::::- more generally any spatial frequency e.g. in cycles per unit length
reciprocal length
reciprocal distribution









































in probability and statistics, the reciprocal distribution, also known as the log-uniform distribution, is a continuous probability distribution. it is characterised by its probability density function, within the support of the distribution, being proportional to the reciprocal of the variable.









































the reciprocal distribution is an example of an inverse distribution, and the reciprocal (inverse) of a random variable with a reciprocal distribution itself has a reciprocal distribution.
