AIt carries energy from place to place
BIt reflects from a hard surface
CIt travels without a medium
DIt can be given a wavelength
Answer & Solution
Correct answer: C. It travels without a medium
1. Sound is carried by the particles of a medium, so it dies out where there are no particles.
2. Electromagnetic radiation can propagate without a medium through which to move, even though it is a wave.
3. That is why sunlight crosses empty space to reach us while sound cannot.
