Use the table to answer question #4.
A student is using a sound machine to produce the sound waves presented in the data table above. How could the student manipulate the sounds to make them match in pitch but make sound wave #1 louder than sound wave #2? (AKS 9a, DOK
The student should make the waves have the same amplitude but sound wave #1 have a higher frequency.
The student should make the waves have the same frequency but make sound wave #1 have a higher amplitude.
The student should make the waves have the same wavelength but sound wave #1 have a higher frequency.

Students in a science class were presented with the model above and told that the solid line is the initial wave and the dotted line is the resultant wave. The students were challenged to use the model to compare the relationship between sound and amplitude of the initial wave and the resultant wave. Which student’s response is the best relationship? (AKS 9a, DOK 3)
Student I: The sound of the resultant wave is louder because the amplitude decreased.
Student II: The sound of the resultant wave is softer because the amplitude decreased.
Student III: The sound of the resultant has a higher pitch because the amplitude decreased.
Student IV: The sound of the resultant has a lower pitch because the amplitude decreased.
