13. Examine the diagram below. Which of these waves would have a higher pitch? Pick the best answer.

• Wave A has a higher pitch because it has a higher frequency
• Wave B has a higher pitch because it has a higher frequency
• Wave A has a higher pitch because it has a higher amplitude
• Wave B has a higher pitch because it has a higher amplitude

14. Look at the diagram below. Which wave is the loudest, and why? Pick the best answer. .

• Wave X is the loudest because it has the smallest amplitude.
• Wave Z is the loudest because it has the greatest amplitude.
• These waves have the same loudness because they have the same frequency.
