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?
The sound wave traveled the fastest through the helium.
The sound wave traveled the slowest through the metal pole.
The sound wave traveled more quickly through the water than the balloon.
The sound wave traveled more quickly through the glass of water than the metal pole.
