Question

4 group the characteristics according to the type of wave they describe. transfer energy can travel through empty space include sound waves must travel through a medium include light waves mechanical waves both electromagnetic waves more

Explanation:

• Mechanical waves: Require a medium (so "Must travel through a medium") and include sound waves (so "Include sound waves").
• Both: All waves (mechanical and electromagnetic) transfer energy, so "Transfer energy" goes here.
• Electromagnetic waves: Can travel through empty space (no medium needed) and include light waves, so "Can travel through empty space" and "Include light waves" go here.

Answer:

• Mechanical waves: Include sound waves, Must travel through a medium
• Both: Transfer energy
• Electromagnetic waves: Can travel through empty space, Include light waves
