what is the wavelength of an earthquake wave if it has speed of 9000 m/s and a frequency of 12 hz? A) 750 m B) 108,000 m C) 0.0013 m D) 9012 m

1 answer

The wavelength (\(\lambda\)) of a wave can be calculated using the formula:

\[ \lambda = \frac{v}{f} \]

where:

  • \(v\) is the speed of the wave,
  • \(f\) is the frequency.

Given:

  • Speed (\(v\)) = 9000 m/s
  • Frequency (\(f\)) = 12 Hz

Substituting the values into the formula:

\[ \lambda = \frac{9000 \text{ m/s}}{12 \text{ Hz}} = 750 \text{ m} \]

So, the wavelength of the earthquake wave is 750 m.

The correct answer is A) 750 m.
