### Particle wave duality

So knowing that every particle also has wave-like properties, would it be possible for a stream of oxygen molecules could also have a diffraction pattern if we measured it at a long enough distance and at a precise enough measurement?

The car/baseball examples are meant to show you that NOT every particle has wave properties. Those that have too much mass give wavelengths below 10-15, oxygen atoms would not actually have wave properties because their mass is too large.

So a car would not have any measurable wavelike properties simply due to its large mass? What quota would an object need to fufill to be considered too large to have measurable wasvelike properties or not?

### Re: Particle wave duality

The detectability of a wavelike properties is dependent upon the wavelength of that object. In lecture the Professor stated that any wavelength smaller than 10^-18m can most likely not be detected. The greater the mass of an object, the less likely that its wavelength will be detected because mass and wavelength have an inverse relationship. You would calculate the wavelength of an object given its mass using the equation wavelength= (h)/(mv)
