Uses of sound waves



In this video, we’ll discuss the properties of both sound waves and seismic waves and some of the fascinating ways in which they’re used.  We’ll look at the use of ultrasound in both medicine and in industry, sonar, animal echolocation and what the study of seismic waves has taught us about the internal structure of the Earth.

Please note that this topic will be examined in the higher tier papers only.
