What is Heisenberg Uncertainty Principle Formula | Quantum Physics

We have lot of things happening around us in just a fraction of seconds. Everything that happen around us, we can relate to physics and the chemistry. The root of everything that happens is the Mathematics. If you are clear with the basic Math’s concepts then you can do better with the Physics and Chemistry. Today here we will know about the heisenberg uncertainty principle class 11 topics.

About Heisenberg Uncertainty Principle definition

Quantum Physics explains a lot of concept and practicality around us. This topic of Uncertainty principle is also one of the important topics from the book of quantum mechanics. Uncertainty Principle in quantum mechanics is also referred to as Heisenberg Uncertainty Principle or it is also known as Heisenberg Indeterminacy Principle. It was expressed by one of the German Physicist Werner Heisenberg in the year of 1927. Heisenberg Uncertainty Principle explains that for any object moving with velocity ‘v’ and at position ‘x’, both the values that is velocity and position cannot be gathered at the same time. This concept of not getting the exact position and the exact velocity has no reference in the nature.

Heisenberg Uncertainty Principle Formula

Indeterminacy in position * Indeterminacy in momentum \geq  h/2π


\sigma_{{x}} \sigma_{{p}} \geq \frac{h_{p}}{2} where is h_{p} Plank’s Constant i.e. h_{p} = \frac{h}{2\pi}

In the real world and visible to eyes this uncertainty principle has no reference.

  • Let us take a car moving on a road, we can measure or note both the velocity and the position of the vehicle. So the uncertainty produced with this principle is very small as compared to such large objects.
  • This rule mostly refers to the extremely small particles of small mass subatomic particles.
  • As per this principle, the product of position and velocity is either greater or equal to the constant (h/2Π) where “h” known as Plank’s Constant with the value h= 6.6 × 10−34 joule-second.
  • This product is significant for the atoms with small masses and subatomic particles.

Why velocity and position cannot be measured simultaneously?

If any experiment is made to check the velocity of particle very precisely, it will knock out the electron in some unpredictable nature and hence it has no significant position at that time.

Every object particle is associated with the wave like properties and behaviors. Hence the particle is mostly located at the intense crust or trough of the wave. A localized wave particle having uncertain velocity and a defined position will have indeterminate wavelength while the wave particle with precise velocity and is not having defined position or is spread out will have well defined wavelength.
