Question

Why can’t we hear each other on Moon?

Answer 1

Answer:

We cannot hear each other on the moon because sound needs a medium like a solid, liquid, or air to travel and the moon is devoid of atmosphere and sound waves cannot travel in the moon.

Explanation:

• Sound waves require vibrations of molecules of a medium to travel and cannot travel through vacuum.
• This is the reason astronauts reaching moon cannot talk with each other on moon’s surface.
• Light waves and radio waves can travel in space and astronauts travelling to space correspond with each other through radio waves.
