A vibrating string 50.0 cm long is under a tension of 1.00 N. The results from five successive stroboscopic pictures are shown in Fig. 15.39. The strobe rate is set at 5000 flashes per minute, and observations reveal that the maximum displacement occurred at flashes 1 and 5 with no other maxima in between.
(a) Find the period, frequency, and wavelength for the traveling waves on this string.
(b) In what normal mode (harmonic) is the string vibrating?
(c) What is the speed of the traveling waves on the string?
(d) How fast is point P moving when the string is in (i) position 1 and (ii) position 3?
(e) What is the mass of this string?
