Physics - Waves

A harmonic wave is traveling along a rope. The oscillator that generates the wave completes 40.0 vibrations in 30.0 s. A given crest of the wave travels 425 cm along the rope in a time period of 10.0 s. What is the wavelength?

  1. frequency=40/30 hz

    wave velocity= 4.25m/10 sec

    frequency*wavelength=wavevelocity
    calculate velocity

  6. Wavelenth = velocity / frequecy
    Frequency=40vibration / 30s=1.33HZ
    425cm *100 = 4.25m
    Then divide 4.25 m by 10 (the period)
    4.35/10 = 0.425 m
    (I am sorry for the previous answer my bad)

  7. Wavelenth = velocity / frequecy
    Frequency=40vibration / 30s=1.33HZ
    425cm *100 = 4.25m
    Then divide 4.25 m by 1.33
    4.35/1.33= 3.19m then divide by 10
    3.19/10 = 0.319
