heisenberg uncertainty principle class 11

This principle is not a statement about the limits of technology, but a fundamental limit on what can be known about a particle at any given moment. Photoelectric effect. The uncertainty principle, developed by W. Heisenberg, is a statement of the effects of wave-particle duality on the properties of subatomic objects. Thus, the mathematical expression for the Heisenberg’s uncertainty principle is … De-Broglie's equation. Repeatability hypothesis The uncertainty principle was introduced by Heisenberg in a paper entitled ‘Über den anschaulichen Inhalt der quantentheoretischen 1Kinematik und Mechanik’ published in 1927. And so if we take a particle, let's say we have a particle here of Mass M, moving with Velocity V, the momentum of that particle, the linear momentum is equal to the Mass times the Velocity.
