The speed of sound is dependent on which of the following?

the medium through which the sound travels

the object that creates the sound

the refraction of the sound

none of the above

Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. The speed of sound in room temperature air is 346 meters per second. so that would be answer A

The medium through which the sound travels (and the temperature of the air)
