period = T = 18.5/23 seconds
speed = 168 centi meters/ 20.21 seconds
distance = speed * time
= (168/20.21)(18.5/23)
A harmonic wave is traveling along a string. If the oscillator that generates the wave completes 23 vibrations in 18.50 seconds and if it takes a crest 20.21 seconds to travel 168 cm along the rope. What is the wavelength of the wave? Answer in cm.
