Radio waves are able to be polarised, whereas sound waves are not able to be polarised. Which statement explains the reason for this?
- ARadio waves are generally of a higher frequency than sound waves.
- BRadio waves are transverse waves, but sound waves are longitudinal waves.
- CRadio waves can travel through a vacuum, but sound waves cannot travel through a vacuum.
- DRadio waves travel at a much higher speed than sound waves.
