This is because the wavelength is too small relative to the moving object to be observed. This is due to Planckâ€™s constant being small, so when we use it in equations (where wavelength is proportional to Planckâ€™s constant and inversely proportional to mass) with large objects (as compared to very tiny subatomic particles), wavelength is actually extremely small.
