**HEISENBERG’S UNCERTAINTY PRINCIPLE:**

- This principle was in favor of the wave nature of matter
- It stated that it is impossible to simultaneously evaluate the precise position and momentum of particle. There is always some
**probability**in predicting the position and momentum of a particle. Mathematically, it can be written as:

* (Δx)(Δp) ≥ h/(2π)*

Considering the above equation, 2 cases are possible:

**Case-1**- If precise momentum(p) of an electron is known, then its wavelength by De Broglie’s hypothesis will be constant:

* λ = h/p*

It means that the wavelength has a fixed value and the wave is extended infinitely throughout the wave. Hence, it is impossible to find the position of the wave.

Mathematically, if ** p = fixed , **Then,

*Δp→0, Δx→∞***Case-2**- If the wave is localized, having finite end points

A localized wave is shown below:

As we can see in the diagram, the wavelength (λ) is not fixe
