Interpretation of Klein-Gordon equation

[snoopies622]

Comparing the Klein-Gordon equation to the equation of motion for a classical harmonic oscillator, I notice that for a particle of mass m,

$$\frac {mc^2}{\hbar}$$

is a frequency.

Does this frequency have a physical meaning?

That is the compton frequency.
