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

When was Dallas Wiens born?
Dallas Wiens was born on 1985-05-06.
What is the rate of change of displacement?
constant speed
Which describes the average velocity of a bicycle going at a constant speed in constant direction?
The total displacement divided by the time. The slope of the displacement vs. time graph.
When did Wolfgang Wiens die?
Wolfgang Wiens died on May 17, 2012, in Hamburg, Germany.
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 time rate of change of displacement?
constant speed
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 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
When was Jeff Wiens born?
Jeff Wiens was born on August 29, 1974, in Des Moines, Iowa, USA.
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?
Velocity = Displacement/Time =10.55m/11.31s = 0.932m/s Value of constant velocity is 0.932m/s.
If displacement of a particle is zero?
If displacement of a particle is zero in a uniform circular motion, then the distance travelled by that particle is not zero, kinetic energy is constant, speed is constant and work done is zero
