Knowledge in dynamics and in waves' theoryThis Demonstration shows the propagation of spherical elastic waves, commonly known as seismic waves, from a point source. Shown here are two types of seismic waves: pressure wave (P-wave) and shear wave (S-wave). The P-wave is longitudinal, and thus oscillates along the direction of the wave propagation, while the S-wave shakes perpendicular to the travel directionComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Física
