WebProblems 1. How would you distinguish between Love waves and Rayleigh waves if you were given an earthquake record from a WWSSN station? 2. What is the wavelength of a surface wave with a period of (a) 10 s, (b) 100 s and (c)200 s? Comment on the use of surface waves in resolving small-scale lateral inhomogeneities in the crust and mantle. 3. WebRayleigh waves are well suited for use in a variety of transducer † which process radar, television, and radio signals. Of primary importance is the fact that, for a given frequency, the wavelength of an electromagnetic wave is about 10 5 times greater than the wavelength of a Rayleigh wave. This follows from the basic kinematic relation (Section 17.2) cibc banking app for laptop

WebSeismic Waves. When an earthquake occurs, it makes seismic waves, ... There are two major kinds of surface waves: Love waves, which are shear waves trapped near the surface, and Rayleigh waves, which have rock particle motions that are very similar to the motions of water particles in ocean waves. WebRayleigh-waves. Rayleigh-waves might be a type of shock wave to occur in an earthquake that you haven't heard of before. Rayleigh-waves travel across the Earth's surface in an elliptical pattern. As a result of this, Rayleigh-waves have a horizontal and a vertical component to their shock waves. Fig. 5: A Raleigh-wave in action.
