Question

Where do sound waves travel faster? (1 point)
through less dense materials, because the molecules in a loosely packed medium collide less frequently
• through less dense materials, because the molecules in a loosely packed medium collide more frequently
O through denser materials, because the molecules in a tightly packed medium collide more frequently
O through denser materials, because the molecules in a tightly packed medium collide less frequently

Answer 1

through denser materials, because the molecules in a tightly packed medium collide more frequently

Sound generally travels faster in denser/solid media (solids > liquids > gases) because particles are closer and transmit vibrations (pressure changes) more quickly—stiffer, tightly packed materials transfer the disturbance faster.
