Is string open at both ends same as closed at both ends?

Does this even make sense? lol. I know for this case wavelength = 2L/n but are both cases the same (if indeed it makes any sense)?

I know what you are getting at. YES the equations are the same, but NO they are not the same. I doubt you need to know the specifics but here are some basics that might be helpful. Closed at both end are like in string instruments, open at both ends are in types of wind instruments. Closed have a node at each end, open have an antinode at each end. Besides this I don't think there is much else to know in terms of differences.

you can't really have a string open at both ends producing harmonics now can you lol

Well stated. The math works out to be similar, but the devices are generating sound differently. For harmonics questions on the MCAT, I'd think of the as the same.

I'm guessing the pipe closed at both ends would be great for holding cold beverages though. 😀
