A harmonic wave is traveling along a rope.
The oscillator that generates the wave com-
pletes 48.0 vibrations in 25.8 s. A given crest
of the wave travels 413 cm along the rope in a
time period of 10.5 s.
What is the wavelength?
Answer in units of m

  • physics -

    The wave speed is
    V = 4.13m/10.5 s = 0.393 m/s
    The frequency is
    f = 48/25.8 = 1.86 s^-1

    Use the relationship
    L = V/f to get the wavelength, L , in meters
