Yes, that's correct. Weber's law states that the just noticeable difference (JND) between two stimuli is proportional to the intensity of the initial stimulus. This means that the difference needed to perceive a change in stimulus intensity remains constant regardless of the initial intensity level.

What is the definition of weber's law?
Weber's law states that the just noticeable difference between two stimuli is proportional to the magnitude of the stimuli. In other words, the change in stimulus needed to detect a difference is a constant ratio of the original stimulus level.
What is the difference between a control variable and a control treatment?
A control variable is a factor that is held constant in an experiment to prevent it from influencing the outcome. A control treatment, on the other hand, is a specific group or condition in an experiment that receives no experimental manipulation and is used as a baseline for comparison with the treatment groups.
How can you tell if one variable is directly proportional to another variable?
Two variables are directly proportional to each other if they increase or decrease together at a constant rate. In other words, if you plot the relationship between the two variables on a graph and the points lie on a straight line passing through the origin, then they are directly proportional. Mathematically, this can be expressed as y = kx, where k is a constant.
Is it ironic to be in a constant state of cognitive dissonance?
Yea
What is the difference between a test and an experiment?
A test is used to determine the performance, reliability, or function of something, while an experiment is a controlled procedure undertaken to discover, test, or demonstrate something. In a test, variables are usually kept constant, whereas in an experiment, variables are intentionally changed to observe their effect.
The principle that two stimuli must differ by a constant proportion for their difference to be perceived is known as?
Weber's Law"Ernst Weber noted that for people to really perceive a difference, the stimuli must differ by a constant "proportion" not a constant "amount."

Definition: In a direct proportion y = kx, the number k is called the constant of ______.?
proportion
What is the direct proportion?
Two variables, X and Y, are said to be in direct proportion if X/Y is a constant. Equivalently, Y = cX for some constant c.
In a direct proportion y kx the number k is called the constant of .?
It is the constant of proportionality.
What is the definition for constant of proportionality?
The state of being in proportion.
Why does coherent light have a relatively constant intensity?
Coherence relates to the physics of waves. Specifically, it refers to a property that allows constant interference. Because interference varies the intensity of light, coherent light has a relatively stable intensity.
What is the direct proportion formula?
x and y are in direct proportion if there is some positive constant c such that y = cx
Who scientist verified law of constant proportion?
Joseph Proust.
Give an example of direct proportion?
The Circumference of a circle is directly proportional to the diameter. The constant of proportion is 'pi = 3.141592....'. Another one is force is directly proportional to mass. The constyant of proportion is acceleration.
What does constant of proportion mean?
If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them. In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.
