    No, p=0 would make the wavelength infinite.

    Then we also use the equation E^2=m^2c^4+p^2c^2 to find its energy from its rest mass, then we plug that into E=hv to find that it still has frequency.
    Doesn't E=hv only apply to photons? If not, you would have to take the velocity into account. Which is zero. So the frequency would be zero.
