Homework 7

Textbook Problems: 42-24, 42-47, 42-21

Problem

An electron is located with an uncertainty in position of $\Delta x = 1.0 \times 10^{-11} \, m$.

1) What is the uncertainty $1 \, s$ later?

2) Sketch a possible shape for the wave packet at time t=0 and at time $t= 1 \, s$.

Questions

Give short (1/2 to 1 pages) answers to the following questions:

1) Why does the concept of Bohr orbits violate the uncertainty principle?

2) What is the physical significance of the wave function $\Psi$?

3) Why is the wave nature of matter not more apparent to our daily observations?
