ASVAB General Science Sound Waves Practice Test 546416

Question 2 of 5
Vibration

A vibrating object produces a sound wave that travels outwardly from the object through a medium (any liquid or solid matter). The vibration disturbs the particles in the surrounding medium, those particles disturb the particules next to them, and so on, as the sound propagates away from the vibration.

A major difference between sound waves and light waves is which of the following?

a sound wave cannot travel through a vacuum

a sound wave is mechanical while a light wave is electromagnetic

all of these are correct

a sound wave is much slower than a light wave
