Distinction between waves and particles.
It is essential that one understand the distinction between waves and particles. A classical particle is something that has: position, momentum, kinetic energy, mass and electric charge. A classical wave has the attributes of: wavelength, frequency, velocity, amplitude of the disturbance, intensity, energy and momentum.
The most distinctive difference between the two is that a
particle can be localized, whereas a wave is spread out and
occupies a relatively large position of space. There is one
important difference between photons and massive objects in the
way their waves and particles are related. Because
for a
photon, only one rule is required to get both wavelength and
frequency from a photon's particles of energy and momentum. A
massive object, on the other hand, requires separate rules for
its wavelength
and frequency ![]()
A brief description of the wave matter.
The subject of matter waves cannot be treated meaningfully without employing far greater mathematical sophistication than has been necessary heretofore. The reader will encounter functional notation, operators, partial differential equations, probability, and so-called complex algebra.
Since a traveling wave moving in both directions this functional relation can be generalized too,
![]()
Obtaining by the second-order partial differential equation for y with respect to x and t, we have,
![]()
Since the equation is linear, any linear combination of solutions will also be a solution. This implies the principle of superposition and gives the usual method of forming a standing wave by a linear combination of traveling waves moving in opposite directions.
The Schrödinger equation.
Since the concept of matter waves is not a result of previous physical theories, it is impossible to derive the corresponding wave equation for a particle. We are using the wave model, however, and the equation is developed in a manner analogous to that used for other waves.
The dependent variable of a matter wave is called the wave
function and is denoted by
(called capital psi).
From the equations,
and ![]()
The propagation number of a wave is proportional to the momentum of the particle and the angular frequency is proportional to the energy; therefore we can write;
![]()
Using the Moivre's theorem, expressing
in exponential;
differentiated with respect to x and t,
![]()
The partial derivatives with respect to x and t, are connected by means of the relation between the energy and the momentum.
The total energy and momentum are related by the expression for energy conservation of a particle,
![]()
To obtain the wave equation is multiplied by
and
the differential operators
and
are
substituted for p and E. We obtain,
![]()
This is the Schrödinger equation for one-dimensional matter
waves. This equation differs from the classical wave equation by
having a term with no derivative
. In addition the Schrödinger
equation contains i, which makes it a complex equation.
In particular, the complex nature of
indicates that
cannot
be observed like the displacement of a string and also means that
we should not look for a medium which transmits our matter waves.
There is no "ether" for matter waves, as opposed to the
existence of, say, water for water waves.
I want to point out, that the correspondence with the new
established classical ideas ,
is classically no longer
a complex, but a real number.
Through the correspondence principle keeps the theory of an analogy to the classical wave equation.
There is some conflict between previous classical ideas and those of the theory of matter waves. For example, the concept of a classical trajectory of a particle must be discarded and replaced by a probability distribution spread over a large region of space. But, with the application of Freire's enunciated that major flaw in the development of the wave theory of matter, no need the probability to find out the particle position in a certain region.
Because the wave is spread out and occupies a relatively large position of space, I would say equivalent to an expansion of (nq*Y) in the space. That is why it is need to find out the particle through the probability.
For example, in this problem on the Michel.fr4 program for
, we
have
![]()
We observe that the coordinate (Y) is divided by the number (nq),
to obtain the real particle's location and the application of
Freire's enunciated
.
