### 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.

### Re: de brogile equation

When dealing with Electromagnetic radiation (light) its useful to use the light equations : E=hν and c=λν, but keep in mind that these equations are specific to EM radiation. This is where De broglie's equation comes into play when dealing with the other particles (that have mass). De broglie's equation can be applied to electrons, protons, atoms ,etc. but at a certain point it becomes easier to just think of objects as more particle-like than wave-like since wavelength decreases as mass increases, even if they are technically both.

So does that mean that De Broglie's wave equation works for any particle with momentum or would the particle also need to have wavelength properties?
