- Homework Statement
- You and a friend each have one rope. You tie the two ropes together
and stand as far apart as possible, each holding one end
of the new longer rope and pulling to put it under tension. You
then begin moving your arm in such a way as to produce a harmonic
wave with a wavelength of 1.0 m. Your friend looks at
the waves as they reach her arm. Is it possible that she measures
a wavelength of (a) 0.8 m, (b) 1.0 m, or (c) 1.2 m?

I think I know what this problem means, but not sure how can I do quantitative work to solve it.
I think only a would work because of friction of string, the reflected waves from the junction between two strings like that.
Although, I am not sure how can I build the process, but this was my guess...
