In Wien's experiment it was found that when the temperature of the source increases, then the wavelength for which the radiant energy becomes maximum decreases. This displacement towards the lower wavelength side as temperature increases is termed as displacement law.
So if T, the temperature of the source in kelvin and lambda m is the wavelength for which the energy is maximum. Then lambdam *T = constant. This constant is known as Wien's constant, whose value is 5.67 x 10-8 mK.

Why the displacement time graph is parabola?
The nature of displacement-time graph is parabolic if the acceleration is constant(uniform). When acceleration is constant, displacement is directly proportional to the square of time which results into a parabolic structure of graph.
What is the formula for calculating displacement in which initial velocity and time are the variables?
If the velocity is constant, thenDisplacement = (initial velocity) multiplied by (time)
Why does a constant speed have a slope of 0?
Because the slope measures the rate of change. The word "CONSTANT" means no change so there is no rate of change. Having said that, it will not have a slope of zero if you are plotting displacement against time.
What is constant speed in mathematical terms?
It's when the rate of change of distance per unit time is constant. Speed (or more precisely, velocity) is represented by the differential equation ds/dt, where s = displacement (actual distance travelled), and t = time taken
What is the result of adding a displacement vector to an another displacement vector?
another displacement
Why wiens law is called wiens displacement law?
Wiens Law is known as Wiens Displacement Law because it describes the relationship between the temperature of a blackbody radiator and the peak wavelength of the radiation it emits. It shows how the peak wavelength shifts to shorter values at higher temperatures and vice versa, hence the term "displacement."
When was Dallas Wiens born?
Dallas Wiens was born on 1985-05-06.
When did Wolfgang Wiens die?
Wolfgang Wiens died on May 17, 2012, in Hamburg, Germany.
What is the rate of change of displacement?
constant speed
When was Jeff Wiens born?
Jeff Wiens was born on August 29, 1974, in Des Moines, Iowa, USA.
What is the mathematical relationship between force and displacement?
For a simple harmonic oscillator, the force is proportional to the displacement F=-kx, where F is the force, x is the displacement, and k is a positive proportionality constant commonly referred to as the spring constant
What is the value of this constant velocity if an object travels at a constant velocity for a time period of 11.31 s over a displacement of 10.55m?
The value of the constant velocity is the displacement divided by the time taken, which is 10.55m / 11.31s = 0.932 m/s.
What does the spring constant k mean?
The spring constant is a measure of stiffness - the ability to resist displacement under a load. It is denoted by K where F = kx where f = load force and x = displacement
Is the displacement time graph of a body moving with uniform velocity always a straight line?
A displacement vs. time graph of a body moving with uniform (constant) velocity will always be a line of which the slope will be the value of velocity. This is true because velocity is the derivative (or slope at any time t) of the displacement graph, and if the slope is always constant, then the displacement will change at a constant rate.
What are the release dates for Lord of the Wiens - 2005?
Lord of the Wiens - 2005 was released on: USA: 25 November 2005 (TV premiere)
What is the difference between a positive and non-positive displacement pump?
A positive displacement pump moves a constant volume of fluid for each cycle of operation, creating flow by direct displacement. In contrast, a non-positive displacement pump does not move a constant volume of fluid per cycle and relies on factors like speed and pressure to generate flow.
What has the author A K Wiens written?
