INTRODUCTION

A mechanic wave is a mechanical disturbance that propagates through a medium such as air, water, or solids, carrying energy and information via oscillations of pressure and particle displacement. Each medium of propagation present its own characteristics.

Mechanic waves can be categorized based on their propagation mode, frequency range, and the medium through which they travel.

• Longitudinal Waves: These waves feature particle oscillations parallel to the wave’s direction of travel. They are prevalent in fluids (both gases and liquids) and can also propagate through solids. Longitudinal waves are characterized by alternating compressions and rarefactions of the medium.

• Transverse Waves: In these waves, particle motion is perpendicular to the wave’s direction of propagation. Transverse waves are exclusive to solid media, where shear deformation is supported. They are significant in understanding the Earth’s interior and the mechanical properties of materials.

• Surface Waves: Occurring at the boundary between two distinct mediums, surface waves combine aspects of both longitudinal and transverse waves. They diminish in amplitude with depth in the medium and are essential in applications like seismology and surface acoustic wave devices.
