Kim is doing an experiment with sound waves. she tested to see how quickly a sound wave could travel through three different materials: a metal pole, a helium balloon and a glass of water. she recorded her results. which of the following is most likely true? group of answer choices the sound wave traveled more quickly through the water than the balloon. the sound wave traveled the slowest through the metal pole. the sound wave traveled the fastest through the helium. the sound wave traveled more quickly through the glass of water than the metal pole.

Explanation:

A sound is produced by vibration. These vibrations are called "sound waves." In order for sound waves to travel, it needs a particular medium. This medium can either be solid, liquid or gas.

Remember that sound waves travel faster in a "solid medium," because this matter is denser than the other two. Sound waves travel faster in liquid than in gas, because water is densely packed with particles than gas (such as air).

In the situation above, the answer is "The sound wave traveled more quickly through the water than the balloon." As I've mentioned earlier, sound waves travel faster in liquid than in gas. Thus, the sound waves traveled faster through the glass of water (liquid) than the helium (gas) balloon.
