Question
Suppose you and your friend are on the moon. Will you be able to hear any sound produced by your friend?
Answer
No, you will not be able to hear any sound produced by your friend on the moon.
Reason:
Sound waves need a material medium (like air) to travel.
There is no atmosphere (vacuum) on the moon.
Due to the absence of a medium, sound waves cannot propagate, and hence, you cannot hear each other directly.
(Astronauts use wireless radio systems to talk to each other on the moon.)
