string pulse data

Ok on that first lab we did the other day where we measured the pulses and the tension, I am unsure on where to start my calculations. I measured the before and after lengths of the rubberbands we used, the length of the penedulms, how many ""hits"" there was, and found the force in Newtons. Can you give me some tips are where to start now?

Can you give me the specific data?

I'm not sure what you mean by 'before' and 'after' lengths of the rubberbands. Other than that you seem to have everything, but give me your specifics so I can tell you for sure.
