Question

7. [2pt] How is the wave speed, v, related to the one-way travel time, tp, and the slinky length, L? Choose all the correct answers. A) v = tp/L B) v = L/tp C) v = 2tp/L D) v = 2L/tp Answer: -------------------------------------------------------------------------------- 8. [2pt] Substitute your result from the previous question into fm=mf1 (the allowed standing-wave frequencies are all integer multiples of the fundamental frequency) and produce an equation involving only f, tp, and n. If you plotted a graph of f on the y axis and n on the x axis, what would the slope be? A) 1/tp2 B) 1/(2tp) C) tp/2 D) tp

Explanation / Answer

7)b v = L/tp 8) B) 1/(2tp)
