Sound is a waveform made from vibrating matter. The sound wave travels through matter—especially air—in a straight line. When the wave hits a different material, some of it is reflected, absorbed and transmitted through the material. In the case of a sound wave in air hitting a solid wall, most of the sound is reflected.
increase the energy give a sound wave what changes: If a wave's fourth harmonic has a frequency of 40 Hz, what is its natural frequency and what is the frequency ofH6?
Sound Waves. Sound waves are caused by vibrating particles and are an example of a longitudinal wave. Human ears are specially adapted to hear sound waves and we can make use of certain types of sound waves called ultrasound waves in medicine and echolocation technology.
