Weber's law states that the size of a just noticeable difference (JND) is proportional to the intensity of the stimulus. It means that the JND between two stimuli is not constant but depends on the intensity of the stimuli. In this case, the difference between one pound of sand and five pounds of sand is greater than the difference between 500 pounds of sand and 505 pounds of sand, which is consistent with Weber's law.
