Before watching this video, please ensure that you have understood the concepts covered in Topic 5 (Waves in matter), particularly those in the Sound waves and Ultrasound videos.

In this video, we’ll discuss the properties of two different types of longitudinal waves – sound waves and seismic waves – and some of the fascinating ways in which they’re used.

Please note that this is a higher tier-only video.
