Question 3 Page 163 - Chapter 12 Class 9 - Sound

Last updated at April 16, 2024 by

Suppose you and your friend are on the moon. Will you be able to hear any sound produced by your friend?

Answer 

The moon has no air or atmosphere at all. It is all vacuum.

Since sound cannot travel through a vacuum, therefore we cannot hear the sound produced by our friend.
