Detailed Solution

The above statement is False.
A sound wave is produced due to vibrations of different objects, so it needs a medium to propagate, and as there is no atmosphere on the moon, there is no medium for the propagation of sound waves. Hence, you can’t talk on the moon as you will not be able to hear your friend’s voice.
The correct statement would be that you cannot hear your friend’s voice on the moon.
