| Weber's law |
Discovered by Ernest Heinrich Weber in 1834. States that the smallest detectable change (jnd) in intensity is a constant fraction of the level of stimulation. Georg Fechner turned Weber's law into a psychophysical logarithm of the magnitude of stimulation (I), or S = k log I. A great deal of psychophysical research has attempted to establish the Weber-Fechner law for sensory dimensions other than intensity, eg, frequency and duration in audition. ...

(Wb) Unit of magnetic flux. One weber is the amount of flux that when linked with a single turn of wire for an interval of one second will induce an electromotive force of one volt.

| Weber's law |
The thesis that perceptual systems respond in such a way so as to make the ratio between the minimum perceptible change in a physical magnitude and the absolute value of that magnitude a constant. For example, Weber's law predicts that smallest detectable intensity difference between two lights will be larger on a bright background than a dim one. This conclusion is approximately true for high light levels.
