As Maria and Carl stood in the kitchen talking, a car drove by the house. The music was blaring so loudly that Maria commented: "That loud music makes it seems like my heart is beating with the music!" "Well, something is beating with the music," shouted Carl. "Look at the windows!" The windows in the kitchen were vibrating to the beat of the music from the car. What is the MOST accurate explanation of the vibration of the windows?

A) Sound waves echo through air.

B) Sound is the vibration of matter.

C) Sound waves push particles back and forth.

D) Sound waves transmit energy as compression waves.

sound is the vibration of matter, because of the particles in the surrounding medium.

Explanation:

sounds waves form when the vibration of an object causes the surrounding medium to vibrate. a medium is the matter the wave travels through, like air. when the sound waves move through the medium, its particles vibrate back and forth, so the vibration of the medium causes the vibration of the windows.

B) Sound is the vibration of matter.
