What is range of the wave-lengths of audible sound in air? As the air particles are pushed together a compression is formed. Speed of Sound Waves Two factors affect the speed of sound waves: – Density of the medium – “Stiffness” of the medium → atomic “springs” Solids and liquids are more rigid than gases – So sound waves move faster! Whether you're talking out loud or texting on your phone, there's going to be a wave transmitting information. Material through which a wave travels. Types of waves. Any disturbance that complies with the wave equation can propagate as a wave moving along the x-axis with a wave speed v. It works equally well for waves on a string, sound waves, and electromagnetic waves. Before sharing sensitive information, make sure you're on a federal government site. via the mechanism of particle-to-particle interaction, a sound wave is characterized as a mechanical wave..
