Question

State Heisenberg's uncertainty principle. Give its mathematical expression.

Answer 1

Heisenberg's uncertainty principle- It states that the position and momentum of microscopic moving particles cannot be determined simultaneously with accuracy or certainty.

Mathematical expression-

$\Delta x\times \Delta P>or=\frac{h}{4\pi }$

$\Delta x=$ uncertainty in the position

$\Delta P=$ uncertainty in the momentum

$h$= Planck's constant.
