Question : A bomb explodes on the moon. You will hear its sound on the Earth after _____.
Option 1: 20 minutes
Option 2: 2 hours and 20 minutes
Option 3: 3.7 hours
Option 4: You cannot hear the sound of explosion
Correct Answer: You cannot hear the sound of explosion
Solution : The correct option is you cannot hear the sound of an explosion.
The medium through which sound travels affects its speed. Since there is no air or other medium for sound waves to travel through in space, the sound of a bomb exploding on the moon cannot be heard from the Earth. Sound needs a medium to travel through, such as air, water, or a solid body.
