Description:
In engineering the checking of the quality of materials is an important task. A cheap way of testing materials where the material to be tested is not destroyed is based on the reflection of sound on interfaces.
Information and ideas:
These tasks are good for showing how behaviour of sound is used in practice.
Furthermore, internet research is good for explorative learning.
Relevant for teaching:
Sound/acoustics: parameters
Vibration and waves
