Question

If you shout on the moon, will the sound travel faster or slower than on earth? Why?

Answer 1

1. Sound waves always need a medium to travel from one place to other.
2. As the moon doesn't have any atmosphere, the sound will not be able to travel at all.
3. The earth has its own atmosphere, so the sound waves will travel faster.
4. Therefore, if you shout on the moon, the sound waves will travel slower than on earth.
