Question

Heisenberg Uncertainty Principle: Compare the relative uncertainty in position and momentum for a plane wave and a wave packet. How do the uncertainties in position and momentum compare? Why? Section 5.3 might be helpful.

Relative to a plane wave, a wave packet has -______(fill in the blank)_______ momentum and -______(fill in the blank)_______ energy…

Answer 1

statement for heisenberg uncertainity principle is :it states that the more precisely the position of some particle is determined, the less precisely its momentum can be known, and vice versa.

The position and momentum of a particle cannot be simultaneously measured with arbitrarily high precision. There is a minimum for the product of the uncertainties of these two measurements. There is likewise a minimum for the product of the uncertainties of the energy and time.
