When a particular wire is vibrating with a frequency of 4.7 hz, a transverse wave of wavelength 71.9 cm is produced. determine the speed of wave pulses along the wire. answer in units of m/s?
The relationship between frequency, wavelength and speed of a wave is given by [tex]v=\lambda f[/tex] where v is the wave speed [tex]\lambda[/tex] is its wavelength f is its frequency
for the wave in our problem, [tex]f=4.7 Hz[/tex] and [tex]\lambda=71.9 cm=0.719 m[/tex], so the speed of the wave is (using the previous equation) [tex]v=\lambda f = (0.719 m)(4.7 Hz)=3.38 m/s[/tex]
