Heisenberg Uncertainty Principle - Statement

Heisenberg’s Uncertainty principle states that it is inherent uncertainty in the act of measuring a variable of a particle. The principle is applicable to the position and momentum of a particle. According to the principle, more precisely the position is known, the more uncertain is the momentum and vice versa.

Heisenberg’s Uncertainty principle is applicable to energy and time. These uncertainties always exist in conjugate pairs such as momentum/position and energy/time. The mathematical representation of this is given as:

$Delta pDelta xgeq frac{h}{4pi }$ $Delta tDelta Egeq frac{h}{4pi }$

In both the equations mentioned above, Δ refers to the uncertainty of the variable and h is Planck’s constant.
