Unformatted text preview: confirms that the earthquake came from San Francisco. Given the P-wave and S-wave have the same source, explain which parameters in the wave equation will change, and which must remain the same. The variable y will no longer represent the displacement in the same direction as the wave is traveling, but instead represent the displacement up-and-down. Because the wave source is the same, the frequency will also be the same. The same argument could be made about amplitude, but it doesn’t account for a source moving different magnitudes in different directions, or energy density, or different directions, so nothing need be said about amplitude. The velocity has changed while the frequency has stayed the same, so the wavelength must change, because wavelength is the product of velocity and period....
