Madeline is playing the guitar. When she moves her fingers across the strings, the strings vibrate. Then sound waves travel through the air to Madeline’s ear, and she can hear the guitar

• The vibrating strings send tiny pieces of sound to Madeline’s ears.

• The vibrating strings make the air around them move

• The vibrating strings turn the air around them into sound. d

Sound travels faster in solid than in gas and liquid because___________________.

• Solid particles are closed to each other allowing particles to move quickly in response to vibration.

• Solid particles are far from each other allowing quick response to vibration.

• Solid are particles are very far from each other allowing quick movement of particles in response to vibration.
