seismic wave. A seismic wave is an elastic wave generated by an impulse such as an earthquake or an explosion. Seismic waves may travel either along or near the earth's surface (Rayleigh and Love waves) or through the earth's interior (P and S waves).Share this page: 1  Facebook.2  Twitter. seismic wave is an elastic wave generated by an impulse such as an earthquake or an explosion.

A transverse wave is when the wave is vibrating perpendicular to the direction the wave is traveling. A longitudinal wave, also called a compression wave, is a wave in which the vibration is in the same direction as that in which the wave is traveling. How frequently a wave or vibration occurs during a span of time, determines the waves frequency. Frequency is the number of waves per unit time. The unit for frequency if a Hertz ( 1/second). The speed a wave travels is the wavelength multiplied by this frequency. The amplitude of a wave is the maximum distance the wave is displaced. Waves are characterized by several distinct behaviors. One behavior is interference. Wave will combine with each other, causing an interference.
