Use sound-wave questions to identify longitudinal waves, distinguish them from transverse or electromagnetic waves, and recognise reflection or refraction.
This question is about sound waves.
Sound is an example of a type of wave.
State the name of this type of wave.
longitudinal;
The speed of sound in liquids is greater than the speed of sound in gases.
Suggest why the speed of sound in liquids is greater than the speed of sound in gases.
- sound travels by vibrations
- vibrations / sound / waves / energy are passed on more effectively because particles are closer together
Accept:
- oscillations for vibrations
- sound vibrates particles
- faster / easily / efficiently for effectively
