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
