Question

Meteor Infrasound A meteor that explodes in the atmosphere creates infrasound waves that can travel multiple times around the globe. One such meteor produced infrasound waves with a wavelength of 6.5 km that propagated 8830 km in 8.47 h. What was the frequency of these waves?

    Answer:

    0.04455 Hz

    Explanation:

    Parameters given:

    Wavelength, λ = 6.5km = 6500m

    Distance travelled by the wave, x = 8830km = 8830000m

    Time taken, t = 8.47hours = 8.47 * 3600 = 30492 secs

    First, we find the speed of the wave:

    Speed, v = distance/time = x/t

    v = 8830000/30492 = 289.58 m/s

    Frequency, f, is given as velocity divided by wavelength:

    f = v/λ

    f = 289.58/6500

    f = 0.04455 Hz
