### Midterm Question: wavelike properties

What does it mean to have measurable wavelike properties?

That the wavelength is able to be measured in an experiment. Large objects do not have measurable wavelike properties

I believe at one point in Dr. Lavelle's lectures he said that anything smaller than 10^-15m would be out of the range of an object being measurable.

I think it's meaning that in order to have 'measurable wavelike properties' it has to be within the range of the electromagnetic spectrum.

In lecture today, Dr. Lavelle shared that in order for something to have measurable wavelike properties, it must have a wavelength bigger than 10^(-18)m. Thus, as described in class, a car would not have measurable wavelike properties as, in the example, its wavelength = 1.64x10^(-38)m. However, an electron does have wavelike properties (as shown in class, the electron had wavelength of 1.4x10^(-10)m, which is detectable in a lab.

### Re: Midterm Question: wavelike properties

Simply put, you can use the De Brolie equation (h/mass*velocity) to find out if the wavelength has measurable properties.
If the wavelength is less than 10^-18m it is not detectable/measurable because it is so small. And like everyone mentioned before, the examples he gave in class are helpful in understanding the concept.
If p is small and divides Planck's constant, the wavelength as a result should usually be relatively be large enough to be detectable.

Thanks thats really clarifying
