Q7: What type of sound waves can propagate in solids ? (a) time period (b) velocity (c) frequency (d) wavelength. Wave Motion: a) The sound waves can also be called as elastic waves and medium is needed for their propagation. This book covers the latest research on wave propagation, giving an in-depth overview on the problem of propagation of waves | InTechOpen. The conversion of Only a few research groups have proposed the use of Helmholtz resonators [4], sonic crystals [5], and polarization-patterned piezoelectric solids [6] for structure-borne or air-borne wave energy harvesting. The objective of our initial investigations is to exploit simple concepts in mechanics such as wave scattering and wave localization in order to concentrate the elastic energy associated with a propagating wave at desired locations. Based on particle displacement of the media, ultrasonic waves are are classified into four types or modes: These waves can propagate through this rods. (iii) Surface or Rayleigh Waves. (d) both inertia and elasticity. B) The velocity of sound waves depends on the property of inertia and Example: Vibration of string, the surface waves produced on the surface of solid and liquid. Their velocity is different for different media. The surface waves travel along the flat or curved surface of thick solids without influencing the bulk of medium below the surface. Q6: The number of oscillations completed in one second is called ______. Seismic waves are elastic waves (low frequency mechanical waves) that propagate in solid or fluid materials. 2 Frequency Equation (2) for the Propagation of Antisymmetric Waves in an Elastic Plate. The third part of the book is devoted to the problems of wave propagation in elastic and piezoelectric media. Solids support two fundamental types of seismic waves: P-waves and S-waves (both body waves). Ultrasonic waves can propagate through a medium as stress or strain waves depending upon the elastic properties of medium. In the fourth part, the works on Analysis of Axisymmetric and Non-Axisymmetric Wave Propagation in a Homogeneous Piezoelectric Solid Circular Cylinder of Transversely Isotropic Materialby Michael Yu.
