1) S-waves are a type of seismic wave associated with earthquakes. They're transverse waves – that is, the disturbance in the crust travels in a straight line path, while the individual rock particles move side to side, perpendicular to the direction of motion. For a strong earthquake, this displacement can be on the order of a few centimeters. The following equation models an S-wave travelling through a uniform segment of Earth's crust: T y(x, t) = = 8 cos(- x + 40πt 103 TT FA Assume that t is measured in second and x is measured in meters. Draw graphs, with appropriate numerical scale markers and units on the axes, to depict a snapshot of this wave at a moment in time and the motion of a single mineral crystal within the crust as the S-wave passes through it. Additionally, determine the speed at which this wave is travelling, and indicate its direction of travel (left/right). Show all calculations.

Transcribed Image Text:1) S-waves are a type of seismic wave associated with earthquakes. They're transverse waves - that
is, the disturbance in the crust travels in a straight line path, while the individual rock particles
move side to side, perpendicular to the direction of motion. For a strong earthquake, this
displacement can be on the order of a few centimeters. The following equation models an S-wave
travelling through a uniform segment of Earth's crust:
y(x, t)
=
π
8 cos(- x + 40πt
103
π
Assume that t is measured in second and x is measured in meters. Draw graphs, with appropriate
numerical scale markers and units on the axes, to depict a snapshot of this wave at a moment in
time and the motion of a single mineral crystal within the crust as the S-wave passes through it.
Additionally, determine the speed at which this wave is travelling, and indicate its direction of
travel (left/right). Show all calculations.
