Measurable wavelength properties

[Katherine Grillo 1B]

Lavelle worked through an example in class about the wavelength of a car moving at a certain velocity. He asked if the car has "any measurable wavelength properties." What does that mean and how do you determine if there are measurable wavelength properties?

[Aidan Ryan 1B]

He is asking whether any wavelike properties would be visible in the cars movement (everything has wavelike movement). I don't remember the exact answer but there will not be any measurable wavelength properties for anything even close to that big.

I would think he just meant if the car had a wavelength that was big enough to notice and detect while moving. For example, when you did the calculation for the wavelength of a car with a mass of 1.5 * 10^8 kg moving at a speed of 27 m/s, the wavelength would be 1.64 *10^-38, which is really small and not big enough for us to really detect or measure. Compared to the wavelength of an electron moving at 5.3* 10^6 m/s, which has a wavelength of 1.4* 10^-10, and is big enough for us to notice.

The object will not have wavelike properties for objects such as 10^-34 because they are to big too big. I believe the maximum it can be is 10^-18 for it to have wavelength properties.

[Rithana Srikanth 3L]

"Measurable wavelike properties" just means wave movement that is noticeable/detectable in a lab. The cutoff point for wavelength detection is 10^-18. In this case, since the object is very big, the wavelength wouldn't be measurable.

The car was too large to have "measurable wavelike properties".
