Answer

Brief Explanations:

  • Electromagnetic vs. Mechanical Waves:
    • Mechanical waves (e.g., sound waves) require a medium (matter) to travel. Since there is very little matter between planets in outer space, mechanical waves like sound waves cannot propagate there.
    • Electromagnetic waves (e.g., X - rays) do not require a medium. They can travel through a vacuum (space with very little matter).
  • Wave - type Identification:
    • X - rays are electromagnetic waves. Sound waves are mechanical waves.

Answer:

an electromagnetic wave, such as an x - ray
