### Measuring Wavelength

I feel like this is a pretty simple question but I can't seem to find it in my notes. So there's a minimum length of a wavelength that's considered to small to be measured but is there a maximum? If so does anyone know what it is?

In class he said the minimum was 10 to the negative 18 and I do not think there is a maximum. He said when it gets so small it is just continuous and you cannot measure the wave length, I am sure this applies at some point when it gets too large but I do not think he mentioned this in lecture.

Most likely there is not a maximum for the length of a wavelength. We most likely will not have to deal with this as it is probably outside the scope of which this class teaches as it was not mentioned in lecture.

I believe that it was specifically mentioned that we should not use anything less than 10^-15

But I have also seen different ranges of what is measurable or not but I would stick to that value from one of his videos

### Re: Measuring Wavelength

He said in class that it would be obvious if a wavelength could be measured or not. He said he wouldn't make the answer something that could be ambiguous and go either direction, so dont worry too much.
