JEE Questions on Heisenberg’s Uncertainty Principle (with solution)

State Heisenberg Uncertainty Principle.

According to the Heisenberg Uncertainty Principle, there is a fundamental limit in accuracy by which property pairs such as position (Δx) and momentum (Δp ) can be known simultaneously. It is given mathematically as Δx⋅Δp≥ ℏ/2, where h is the reduced Planck constant.

How to express Heisenberg Uncertainty Principle mathematically?

We can mathematically express Heisenberg Uncertainty Principle as Δx⋅Δp ≥ ℏ/2, where h is the reduced Planck constant.

What are the components of Heisenberg Uncertainty Principle?

The components of the Heisenberg Uncertainty Principle are:

Δx: Uncertainty in position.
Δp: Uncertainty in momentum.
ℏ: Reduced Planck constant (≈1.054×10^-34 J⋅s

What is Heisenberg uncertainty principle and Schrodinger equation?

Heisenberg Uncertainty Principle: It states the limits on precision of position and momentum measured at a time, which is shown as Δx⋅Δp≥ℏ/2.

Schrödinger Equation: Gives quantum state evolution over time [Tex]\hat H\Psi = E\Psi[/Tex], with as the wave function [Tex]\Psi[/Tex] and [Tex]\hat H[/Tex]– Hamiltonian typical operator .

How do we define the Heisenberg Uncertainty Principle?

We can define Heisenberg Uncertainty Principle as a fundamental principle which states that we can not precisely measure position and momentum of the particle at the same time.

Heisenberg Uncertainty Principle – Definition, Equation, Significance

Heisenberg Uncertainty Principle is a basic theorem in quantum mechanics. It state that we can not measure position and momentum of a particle both at the same time with the same accuracy. It means that if we try to measure the accurate position of a particle, then at the same time we can’t accurately measure the momentum of the particle. Mathematically, the product of uncertainties in position and momentum is greater than h/4π, where h is Planck’s constant. The principle is named after Werner Heisenberg, who proposed this theory in 1927.
