### de brogile equation

in the de Broglie equation why does it state that any moving "particle" , when the examples talk about cars. can any moving object talk have a wavelength?

Yes, anything with momentum has a wavelength, including cars. The example of a car I think was used to demonstrate that literally anything with momentum has a wavelength, but the scales where finding this wavelength is more relevant is when talking about particles.

According to De Broglie, all moving objects have both particle and wave-like properties, but you can only detect the wavelike properties of objects with very small masses and large velocities.

If you are trying to calculate the wavelength of a wave of light (i.e. photon) use the 3 Light Equations: E=hv ; c=h[lambda] ; E=hc/[lambda].
But when dealing with moving objects such as cars or balls you use lambda=h/mv.

Yes any moving object has wavelength, but with large objects such as cars the wavelength is irrelevant.
