Question

After an explosion far away, a person working on a farm first senses vibrations in the ground, then hears the explosion. What accounts for the time between the vibrations and the noise

Answer 1

The vibrations travel faster than noise. When the ground moves it is coming directly from the source, and when you hear it the sound waves are big and take more time to travel.

Answer 2

Answer and Explanation:

After an explosion far away, a person working on a farm first senses vibrations in the ground, then hears the explosion.

Because vibration travels faster than sound.

Vibration is a longitudinal waves directly whereas sound consists compression and rarefactions etc.

So, sound is produced when an object vibrates.

Hence, we senses vibration first then hears the explosion.
