Question

the more energy a sound wave has, the louder the sound. look at the two sound waves below. which wave represents the volume being turned up, wave j or wave k? explain.

Explanation:

Step1: Recall sound - wave property

The volume of a sound is related to the amplitude of the sound - wave. A larger amplitude means a louder sound.

Step2: Compare amplitudes of Wave J and Wave K

By observing the two waves, Wave K has a larger amplitude than Wave J. The amplitude is the maximum displacement from the equilibrium position of the wave.

Answer:

Wave K represents the volume being turned up because it has a larger amplitude, and a larger amplitude of a sound - wave corresponds to a louder sound.
