### De Brogile wavelengths

How can we classify if a particle has any measurable wavelike properties? Why aren't we able to measure wavelike properties of a moving particle if it is too small?

### Re: De Brogile wavelengths

We can measure the wavelike properties of particles but not for everyday objects because the mass is too big. That is why the equation works best for small particles like electrons, because we will have to divide by the object's mass. In the example with the car we calculated it's wavelength to be 1.64 x 10^-38m. But that is an EXTREMELY small wavelength. This would require very advanced and sensitive technology to detect such a small wavelength, but to measure something like that is currently impossible. We can measure small wavelengths but anything 10^-38 is so minute and indistinguishable we are unable to detect it.
