Fechner's Law, proposed by Gustav Fechner, is a psychophysical principle stating that the subjective intensity of a sensation is proportional to the logarithm of the stimulus intensity. This law describes the non-linear relationship between physical stimuli and perceived sensations, suggesting that the perceived intensity grows at a slower rate than the actual stimulus intensity. Fechner's Law forms a foundation for understanding how humans perceive and interpret various stimuli across different sensory modalities, contributing to the field of psychophysics.
