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.

• The student should make the waves have the same frequency but have sound wave#2 have a higher wavelength.

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.

A student holds two vibrating objects. Object A vibrates faster than object B. Which sentence below is true? (AKS 9b, DOK 2)

• A is louder than B

• B is louder than A

• A will have a higher pitch than B

• B will have a higher pitch than A

An oscilloscope is an instrument that can be used to show the wave characteristics of sound. The students used an oscilloscope to display the sound produced when the band's singer sang a note. The display on the oscilloscope is shown below. (AKS 9a, DOK 2)

Which of the following would most likely be shown by the oscilloscope if the same note shown above was sung louder?

Students were asked to compare electromagnetic and sound waves. Which comparison is NOT true? (AKS 9b, DOK 2)

• Sound waves require a medium to travel while electromagnetic waves do not.

• Electromagnetic waves can travel through the vacuum of space while sound waves cannot.

• Electromagnetic waves must have a medium in which to travel, but sound waves do not.

• Sound waves must vibrate matter in order to travel while electromagnetic waves do not require matter to be present.

Ana and Dana were at the beach enjoying the waves. Remembering what they learned in science class, Ana said that the ocean waves were mechanical waves, but Dana said they were electromagnetic waves. Which student is correct and why? (AKS 9b, DOK 2)

• Both of them are right. Ocean waves travel through a medium so it is a mechanical wave. It is also an electromagnetic wave since the particles moves up and down.

• Only Ana is right. Ocean waves travel must have a medium to travel through so it is a mechanical wave.

• Only Dana is right. In ocean waves the particles move up and down which is the characteristic of an electromagnetic wave. Ocean waves need a medium so it is not a mechanical wave.

• Both of them are wrong. Neither ocean waves nor EM waves need a medium.

Which of the following statements correctly compares the speed of waves? (AKS 9b, DOK 2)

• Sound, a mechanical wave is fastest through a vacuum and slowest through solids. Light, which is an electromagnetic wave, is fastest through solids and slowest through a vacuum.

• Sound, an electromagnetic wave, is fastest through a vacuum and slowest through solids. Light, which is a mechanical wave, is fastest through solids and slowest through a vacuum.

• Sound, a mechanical wave, is fastest through solids and slowest through gases. Light, which is an electromagnetic wave, is fastest through a vacuum and slowest through solids.

• Sound, an electromagnetic wave, is fastest through solids and slowest through gases. Light, which is a mechanical wave, is fastest through vacuum and slowest through solids.
