heisenberg uncertainty principle

What is heisenberg uncertainty principle? Heisenberg Uncertainty Principle or indeterminacy principle was given by German scientist Warner Heisenberg according to which position and momentum of an object can not be measured simultaneously.  So if we measure the position of some particle more precisely then its momentum is measured less precisely and vice verse.Heisenberg uncertainty principle can be written as follows If a measurement of position of … Continue reading heisenberg uncertainty principle »
