WebMay 8, 2006 · For example, by Fechner's law, if light A was twice as bright as light B (measured by an instrument), it would appear to the human eye to be log 2 (times a constant to allow for such factors as the units used) brighter than light B. Later experiments have shown conclusively that Fechner's law doesn't generally apply. See Steven’s law. WebFor example, 13.60 = 1.08 X 12.59. The 1.08 stimulus ratio is somewhat obscured because the stimulus intensity is rounded to two decimals. Fechner's law argues that all jnds are …
