Q. Heisenberg's uncertainty principle is in general significant to

TS EAMCET 2021

Solution:

Heisenberg's uncertainty principle states that more precisely we measure the position of a particle, less precisely you can know its velocity and viceversa. It also states that the product of uncertainty in measurement of velocity and uncertainty in measurement of position, is significant to micro particles having a very high speed. The mathematical expression of the law is given below:
$\Delta x \times \Delta y \geq \frac{h}{4 \pi}$
$\Delta x=$ change in position of the particle
$\Delta y=$ change in momentum of particle
$h=$ Planck's constant
