Wavelength Properties

When solving if a certain object has wavelike properties I'm confused why numbers with less than 10^-18 do not show wavelength properties. Can someone explain what this threshold means and what the boundaries of a wavelike property are.

Re: Wavelength Properties

Objects larger than that typically don't have wavelike properties because their momentum and mass are far too large.

Re: Wavelength Properties

In lecture the example of the car not having measurable wavelike properties (1.64 x 10^-38m ), Lavelle said that this number (10^-38) is very small therefore doesn’t show wavelike properties. I'm not sure though, someone correct me if I’m wrong.

Also to elaborate, from the lecture, "All matter has wavelike properties but only noticed for moving objects with extremely small mass (like e-)"

Re: Wavelength Properties

Yes, I believe all matter exhibits wavelike properties, but with our current techniques for measuring these wavelike properties we can only measure it for objects with relatively small mass and momentum, hence the 10^-15 (m) or 10^-18 (m) threshold.
