Answer
**Physical stimuli:** Fechner's law, formulated by the German physiologist and physicist Gustav Theodor Fechner, establishes a mathematical relationship between the physical intensity of a stimulus and the perception or sensory experience it evokes. In simpler terms, the law describes how changes in the intensity of a physical stimulus, such as light, sound, or pressure, correlate with the corresponding changes in our subjective perception of that stimulus.
