- Atransfers energy in a direction parallel to the oscillations: false; requires a medium to travel through: false; always travels at the same speed: true
- Btransfers energy in a direction parallel to the oscillations: false; requires a medium to travel through: true; always travels at the same speed: true
- Ctransfers energy in a direction parallel to the oscillations: true; requires a medium to travel through: false; always travels at the same speed: false
- Dtransfers energy in a direction parallel to the oscillations: true; requires a medium to travel through: true; always travels at the same speed: false
