Moon Talk

Sound waves need a medium like air, water or metal to travel through. They cannot travel in a vacuum.Would it be possible to make a normal conversation on the moon?

Answer is no! Because moon surface does not have any suitable medium to travel through. It is airless and wireless.

Then how did the first astronauts on the moon communicate?

By radio. Radio waves can travel through vacuum. The astronauts have devices in their helmets which transfer the sound waves from their voices into radio waves and transmit it to the ground.
