Waves and oscillations are found in large scales (galactic) and microscopic scales (neutrino) in nature. Their dynamics and behavior heavily depend on the type of medium through which they propagate.
Waves and Oscillations in Nature: An Introduction clearly elucidates the dynamics and behavior of waves and oscillations in various mediums. It presents different types of waves and oscillations that can be observed and studied from macroscopic to microscopic scales. The book provides a thorough introduction for researchers and graduate students in assorted areas of physics, such as fluid dynamics, plasma physics, optics, and astrophysics.
The authors first explain introductory aspects of waves and electromagnetism, including characteristics of waves, the basics of electrostatics and magnetostatics, and Maxwell’s equations. They then explore waves in a uniform media, waves and oscillations in hydrodynamics, and waves in a magnetized medium for homogeneous and nonhomogeneous media. The book also describes types of shock waves, such as normal and oblique shocks, and discusses important details pertaining to waves in optics, including polarization from experimental and observational points of view. The book concludes with a focus on plasmas, covering different plasma parameters, quasilinear and nonlinear aspects of plasma waves, and various instabilities in hydrodynamics and plasmas.

"The range of topics covered in this introduction for researchers and reference volume can be summarized by a list of the nouns appearing just before the word 'waves' in the table of contents: harmonic, electromagnetic, longitudinal, dispersive, hydrodynamic, surface, Poincare and Kelvin, Lamb and Rayleigh, Rossby, MHD, sound, Alfven, magnetoacoustic, solitary, gravity (meaning the kind in a fluid with gravitation as the restoring force), inertial, and shock. ... Specific astronomical applications appear in discussions of radio antennae, ionospheric processes, and shock waves in the Sun, in connection with solar flares and coronal mass ejections. ... Indeed the bibliography is one of the joys of this treatise, including original papers by Hertz, Strutt (Rayleigh to most of us), Brillouin, Compton, Planck, Doppler, Young, Michelson & Morley, Kirchhoff, Babinet, Coulomb, Hall, Oersted, Thompson, Poynting, Taylor, Heisenberg, Einstein, Bohr, Schrodinger, and Poincare. ... On the plus side, the numbers used in some MHD wave problems are appropriate for the solar corona."

"... Since the authors present a very rich compendium on waves and oscillations, the book is not only of an introductory character, but rather a kind of vademecum. It leads the reader through the very rich domain of oscillations and waves, starting from the most elementary simple ones and collecting nearly all chapters in physics, where the problems of oscillations and wave-like phenomena occur. ... The work is an excellent contribution with special aims. Namely, it offers an extremely broad treatment of the problems of oscillations and waves throughout the whole of physics. ... It is meant to be accessible to undergraduates, though readers among the 'elder' researchers also may make practical use of it. This is because the style of the presentation is rather concise; it does not spend too much space for the detailed explanation of the starting points of the cited results. In summary, we are persuaded that this work will be quite valuable for beginners (after obtaining some basic experience) as well as for working professionals."
