A seismic wave is described by the equation
y(x, t) = (7.00 cm) cos [(6.00( rad/cm) x + (20.0( rad/s)t]
The wave travels through a uniform medium in the x -direction.
(a) Is this wave moving right ( + x-direction) or left (−x-direction)?
(b) How far from their equilibrium positions do the particles in the medium move?
(c) What is the frequency of this wave?
(d) What is the wavelength of this wave?
(e) What is the wave speed?
(f) Describe the motion of a particle that is at y = 7.00 cm and x = 0 when t = 0. (g) Is this wave transverse or longitudinal?
