Question

What is an example of the Heisenberg uncertainty principle?

Answer 1

Hint: We need to remember that in this world, the matter is mainly divided into two types. This classification is based on the properties of the matter. There are particles and waves. Heisenberg is the scientist who studies the dual nature of the matter. He is the first scientist to study about the dual behaviour of the particle.

Complete answer:
We must know that the Heisenberg uncertainty principle says, it is impossible to accurately determine the position as well as the moment of a microscopic particle simultaneously.
In the study of position and velocity of the microscopic particle simultaneously it is very difficult and has a lot of limitations.
Heisenberg uncertainty principle formula,
$\mathrm{\Delta }x.\mathrm{\Delta }p⩾{\displaystyle \frac{h}{4\pi }}$
Here,$\mathrm{\Delta }x$ is used to determine the position of the microscopic particle.
$\mathrm{\Delta }p$is used to determine the moment of the microscopic particle.
According to the above discussion, our conclusion is if we study the position of the microscopic particle, definitely velocity should be zero, then we find the position of the particle. Otherwise, if we study the velocity of the microscopic particle means we can’t predict the position of the particle. Here, Heisenberg does not directly discuss velocity, he discusses the moment of the microscopic particle.
Hence, the best example of the Heisenberg uncertainty principle is electrons and protons.

Note:
We know atoms are the tiny particle in the world. Electrons and protons are present in the atom. Electrons revolve and rotate inside the atom in the orbitals. We can't simultaneously study the position and moment of the electron in the atom. Generally particles are localized but waves are delocalised in space. Particles do not interfere with one another, but waves interfere.
