Chapter 7, Problem 7C.4ST

Interpretation Introduction

Interpretation:

The minimum uncertainty in the speed of electron in a one-dimensional box has to be estimated.

Concept introduction:

Heisenberg’s finds that the uncertainty in the position and momentum of a microscopic particle cannot calculated simultaneously.  The simultaneous measurement of uncertainty in the position and momentum is always contains an uncertainty equal to $\frac{h}{4\pi m}$ or more than $\frac{h}{4\pi m}$.
