Question

A harmonic wave is traveling along a rope. The oscillator that generates the wave completes 40.0 vibrations in 22.3 s. A given crest of the wave travels 369 cm along the rope in a time period of 13.5 s. What is the wavelength

Answer 1

Answer:

Explanation:

frequency of vibration

n = 40 / 22.3 per second.

= 1.794 per second

velocity of wave v = 369 / 13.5 cm / s

= 27.33 cm / s

wavelength = velocity / frequency

= 27.33 / 1.794

= 15.23 cm
