An earthquake-produced surface wave can be approximated by a sinusoidal transverse wave. Assuming a frequency of 0.476 Hz (typical of earthquakes, which actually include a mixture of frequencies), what minimum amplitude will cause objects to leave contact with the ground?© BrainMass Inc. brainmass.com March 4, 2021, 6:40 pm ad1c9bdddf
The height, h, of the surface is given as:
h = A Sin[omega t - k dot x + constant]
Here A is the amplitude, omega is 2 pi times the frequency k is the wave vector and x is the position vector.
The wave vector k has a magnitude of 2 pi divided by the wavelength and points in the direction ...
