The formula that relates speed of a wave, v; frequency, f; and wavelength, λ ; is
v = λ f
Therefore
1422 m s = λ 289 H z
λ = 1422 m s 289 H z
The unit Hz is equivalent to s 1 . Therefore the last equation can be simplified as follows:
λ = 1422 m s 289 s 1 = 1422 289 m s s = 4.92 m

The study of seismic waves has improved our understanding of Earth's interior. In general, the velocities of P and S waves indicate the rigidity or stiffness of the material. Faster P and S waves indicate greater rigidity (strength).
Further, S waves cannot travel through liquids because they lack rigidity. Does the velocity of P waves and S waves increase or decrease with increased depth in the lithosphere? The velocity of P waves and S waves ___ with increased depth in the lithosphere.
