Large Objects

Why do larger objects tend to behave less like a wave compared to smaller objects?

Well if you take a look at the De Broglie's formula WaveLength = H/mass*velocity, as mass increases the wavelength is so small that it basically doesn't look or behave like a wave.

All matter has wavelike properties, but the wavelike properties are only noticed for moving objects with an extremely small mass (like electrons).
This can be proven with the De Broglie equation, λ = h/mv --> if the mass is too large, the wavelength will be really small and thus the wavelike properties of that object are not noticeable enough.

And remember! As said during the lecture, anything beyond X * 10^-15 is the limit for what would be too small of a wavelength to be recognized. For example, a baseball had 10^-34 and a car had 10^-38, which is way too small to be measured.

Large objects do have wavelengths which can be demonstrated by De Broglie's equation, but the wavelength is so small that there is no way to measure if there is any properties of waves. The wave length is so small that we just treat it like a particle.

Wavelength properties are most detectable when you "zoom in". Similar to the water example, when water is flowing, it looks continuous, but on the molecular scale, there are separate particles that are not all connected.

I agree with the statements above. In De Broglie's formula, since you are dividing by mass to get wavelength, the inverse relationship would make the wavelength smaller as the object gets bigger in mass.

So, bigger objects have a wavelength way smaller than 10^-15, so they're not detectable according to de Broglie's equation.
