### Measurable wave length properties

In the worked example presented in lecture today when asked if the car has any measurable wave like properties, what exactly helps determine if the answer is yes or no after finding the wavelength?

It depends on the wavelength- if the wavelength is too small, it will not be measurable. Around 10 x ^-18 nm is when wavelengths become measurable. Smaller than that, the wavelengths are not measurable.

Yeah I think Dr. Lavelle's point is that the wavelength is only measurable in a quantum context. It doesn't seem to be something to stress over for the quizzes and tests.

### Re: Measurable wave length properties

You determine yes or no based on the numerical value you get after calculating the wavelength of the object. Extremely small numbers will not have wavelength properties as they are unlikely to be detected.
