Answer to Question #200147 in Physics for jlynn

Question

If the frequency of the vibrator is halved while everything else stays the same, a different standing wave is created. Which of the following statements about the pitch of the sound produced is true? a. The pitch increases, because it is directly proportional to frequency since the velocity doesn’t change. b. The pitch decreases, because it depends on the amount of energy flowing in the waves. c. The pitch decreases, because it is directly proportional to frequency since the velocity doesn’t change. d. The pitch stays the same, because it depends on the amplitude of the wave, which does not change. e. The pitch stays the same, because it depends on the length of the rope and the frequency doesn’t affect the length.

Answer 1

Answer: c. The pitch decreases, because it is directly proportional to frequency since the velocity doesn’t change.
