Question

001 10.0 points As your hand moves back and forth to gener ate longitudinal pulses in a spiral spring, your hand completes 2.6 back-and-forth cycles ev- ery 4.22 s. The velocity of the pulse in the spring is 1.18 cm/s. What is the wavelength? Answer in units of m.

Answer 1

Frequency is the number of cycles gemestecuted por tatil unit time, so The velocity of the wave is defined by V = fx = fx Wewesorgth = Given v= 1.18(mysea=0.6118 mis. - .22sec. n=2-6 cycles. 1-0.0118* 64.22 2.6 = 0.019152307 m. Wavelength (A) = 0.01915 m.
