maturk Posted September 13, 2015 Report Share Posted September 13, 2015 Yooooooooooo! I've once again found another question about waves that I'm unable to answer. This one is from November 2009 HL paper 1. I know how to do number 14, that's a pretty basic one; however, I'm stuck on number 15. The answer is supposed to be B (0.8 cm), does anyone understand how to get to that answer? If so, could you explain? Thank you in advance CHEERS!

HiggsHunter Posted September 13, 2015 Report Share Posted September 13, 2015 The displacements of the beads in Diagram 2 from their initial positions in Diagram 1 are:0cm, 0.5cm, 0.8cm, 0.5cm, 0cm, -0.5cm, etcSo the best estimate of the amplitude is 0.8cm.
