Weber's law states that for a difference to be perceived between two stimuli, the difference must differ by a constant fraction or percentage (rather than a constant amount). This constant fraction is known as the "just noticeable difference" (JND). Weber's law applies to a wide range of stimuli, including brightness, weight, and sound. The law suggests that the stronger the initial stimulus, the greater the additional intensity needed for the second stimulus to be perceived as different.
