Figure 30.66 This figure shows graphical representations of the wave functions of two particles, X and Y, that are moving in the positive x-direction. The maximum amplitude of particle X’s wave function is

$A_0$. Which particle has a greater probability of being located at position

$x_o$ at this instant, and why?

- Particle X, because the wave function of particle X spends more time passing through $x_o$ than the wave function of particle Y.
- Particle X, because the wave function of particle X has a longer wavelength than the wave function of particle Y.
- Particle Y, because the wave function of particle Y is narrower than the wave function of particle X.
- Particle Y, because the wave function of particle Y has a greater amplitude near $x_o$ than the wave function of particle X.
