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

Answer 1

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

(Sound generally travels faster in solids than in liquids or gases since particles are closer together and transfer the disturbance more quickly.)
