### Measurable Wavelengths

Does anybody know how long a wavelength must be to be "measurable"?

I believe in lecture, we were told that for the sake of answering questions that ask if there can be measurable wavelike properties the cutoff is at 10^-18 (even though it is extremely small), but in the lab, it would be rare that anyone measures pat 10^-12.

Yes, the cutoff is at 10^-18

Although Dr. Lavelle said the cutoff was 10 ^-18, he specifically said that we wouldnt have to worry about the cutoff since the answers would be obviously small, like 10^-30
