Praxis 5005 Practice Question
The pitch of a sound is related to which of the following properties of a sound wave?
Correct Answer: B
Rationale: Pitch is primarily determined by the frequency of a sound wave. Higher frequencies correspond to higher pitches, while lower frequencies produce lower pitches.
Option A, speed, refers to how fast the sound travels, which does not affect pitch. Option C, amplitude, relates to the loudness of the sound rather than its pitch; a louder sound can still have the same pitch as a quieter one. Option D, energy, pertains to the overall intensity of the sound but does not influence the perceived pitch. Therefore, frequency is the key property that directly correlates with pitch.
