Answer:
c. Only electromagnetic waves travel through space
Explanation:
Electromagnetic waves are the only waves that travels through space or vacuum.
These waves do not require any material medium for their propagation as the case may be.
- Mechanical waves requires a material medium before they can be propagated.
- But mechanical waves do not require any medium. They readily move through space without any attenuation.
- This is the salient difference between electromagnetic and mechanical waves.
