### measuring wavelength

How can I tell if a wavelength is detectable? Is there a limit for current technologies?

Hello, I believe for this class if we refer to the table Dr. Lavelle showed us in class for the wavelengths should suffice. It starts from the y-rays all the way up to long radio waves.

In addition, I think Dr. Lavelle mentioned that anything less than 10^-18 m is not detectable.

He said anything that is less than 10^-18 is not detectable. He will make it very obvious and it will be an extreme either direction.

Anything below 10^-18 m is too small to measure.

However professor said that he will give either numbers that are super small or super big compared to 10^-18.

### Re: measuring wavelength

Lavelle's rule of thumb is that anything smaller than 10^-18 will be too small to measure. Conceptually, though, if you are working on the atomic scale wavelength will normally be detected and if you are working with objects that can be seen by the human eye, wavelength will not be able to be detected.
