Free Particle Exercise #1

Please answer the  following 3 questions regarding the Physlet:

Function 1 Function 2 Function 3

Description

These animations show the real (red) and imaginary (green) parts of three wave functions. Assume x is measured in cm and time is measured in seconds. 

Questions

  1. Write the de Broglie wave function for the three wave functions in the form:  exp[i(kx-wt)]
  2. What is the mass of the particle? 
  3. What would the mass of the particle be if time was being shown in ms?
