### Conceptual Question on DeBroglie

I understand how electrons and light can have "wavelike properties", but I do not understand how objects such as baseballs and people can act like waves. I understand that you can plug in the object's momentum into de Broglie's equation and get a wavelength, but what are these "properties" and how do everyday objects exhibit them?

Everyday objects do not exhibit properties associated with waves.
This is why the equations for classical mechanics work for everyday objects and the equations for quantum mechanics do not.

The wavelength properties of something like a baseball is something impossible to measure because of its mass and velocity. The wavelength calculated is so minimal that we don't have the technology to measure it. That's why to the naked eye, it looks like theres no wave properties and it is in fact just moving straight

### Re: Conceptual Question on DeBroglie

When you execute the DeBroglie equation with the mass of something like a baseball or car, the resulting wavelength is so extremely small that it is physically impossible to detect. All matter has wavelike properties, but we can only notice these wavelike properties for very small objects with high velocity. Because the wavelength is so extremely small for classical objects, we cannot detect or verify any wavelike properties.
