A ringing bell is sending a longitudinal wave to your ear. What else is true about the longitudinal wave? Check all that apply. All sound waves are longitudinal. Energy is transferred perpendicular to the wave's motion. Mechanical waves can be longitudinal. Electromagnetic waves can be longitudinal. Longitudinal waves require a medium to travel through.

There are three correct answers and these are:

- All sound waves are longitudinal or compression waves. One example of longitudinal waves is seismic waves;

- Mechanical waves can be longitudinal;

- Longitudinal waves require a medium to travel through. Explanation behind this is sound waves are also a mechanical wave so therefore they are also longitudinal.

The correct answers are:

1. All sound waves are longitudinal

3. Mechanical waves can be longitudinal

5. Longitudinal waves require a medium to travel through
