Geneva says that the only thing people need to hear the sounds around them is a vibrating object. Do you agree with her? Explain your answer.
No, I do not agree with Geneva. While a vibrating object is the source of sound, a medium (such as air, water, or a solid) is also required for the sound waves to travel from the source to the listener's ear. Sound cannot travel through a vacuum, so a vibrating object alone is not enough for people to hear it.
