### Wavelike properties in larger objects

When solving the De Broglie equation for an object with a large mass (such as a baseball's mass) the wavelength is so small it cannot be detected. Does this mean that there are no wavelike properties in everyday objects or does it just mean that they are not detectable? If we were to be asked on a test something like "do baseball's have wavelike properties" when the wavelength comes out to something to the -34 power, would we say yes or no?

If the wavelength is that small, then for all purposes then we say the object does NOT have wavelike properties. What we are able to detect dictates what properties we say something has.

Because we can observe electrons forming interference patterns, we say electrons have wavelike properties. Because we also observe things like photoelectric effect, we say electrons have particle-like properties too.

But in no case will we be able to shoot baseballs and find an interference pattern.
