(5-14)   We have the standard deviations, expressing the uncertainties in momentum and position, arising from superposition of waveforms with a range of angular wavenumber, and hence a range of momenta:

σp   =  hkmax / 23π      and         σx  =  0.59 / kmax    


  What happens if we multiply these terms together?

②   What is the significance of this result?
