Question

A student is modeling the relationship between a sound wave's amplitude and its energy. The student will use a series of labeled pictures to illustrate the relationship. Which picture would be appropriate for this model?

A.
a tuning fork vibrating when it is exposed to a particular note

B.
a glass shattering when it is exposed to a high-pitched sound

C.
a dog looking in the direction of a sound humans can't hear

D.
people covering their ears when they hear a loud sound

Answer 1

D. People covering their ears when they hear a loud sound.

Explanation: Amplitude of a sound wave corresponds to its loudness and the energy carried. A loud (large-amplitude) sound causes people to cover their ears, directly illustrating the amplitude–energy relationship.
