WEBER'S LAW

the law postulating that the strength and intensity required to identify modifications within a stimulant is correlated to the absolute magnitude of the stimulant. The ratio of the magnitude of a stimulant to the quantity which importance must be altered in effort for the modification to be interpreted is a constant. This can be shown as A III = k, where / is the original stimulant importance and K is a constant. Therefore, the more severe the stimulant, the greater the modification which has to be made for it to be noticed. Commonly referred to as relativity law.

WEBER'S LAW: "Weber's law states that changes in stimuli will be only noticeable as a ratio of the original stimulant. "
