The correspondence principle provides a prescription to connect quantum physics to classical. It
asserts that the physical quantities evaluated quantum mechanically approach their respective
classical values for large quantum numbers. This has been shown for the pedagogically important
cases of the particle in a box and a harmonic oscillator. However, a particle in a constant field
has a wave function related to the Airy function and has at best been treated numerically. Employing
energy eigenstates we obtain the expectation values of the position, the momentum and their moments
upto fourth order, rigorously and without resorting to numerical or graphical techniques. We compare
them with the corresponding classical values. We also examine the uncertainty product for the
system.
