Answer :
Final answer:
Pitch refers to how high or low a sound is and is determined by the frequency of sound waves. Higher frequencies produce higher pitches, while lower frequencies produce lower pitches. Therefore, the correct answer is option B.
Explanation:
Understanding Sound's Pitch
Pitch is a fundamental characteristic of sound that describes how high or how low a sound is perceived by the human ear. It is primarily determined by the frequency of the sound wave, which is the number of vibrations or cycles that occur in one second, measured in hertz (Hz). A higher frequency means a higher pitch, while a lower frequency means a lower pitch.
For example, when a bird chirps, it produces a sound with a high pitch due to its quick vibrations. In contrast, the roar of a lion has a low pitch since it vibrates at a slower frequency. This can be illustrated as follows:
- High Pitch: The chirp of a bird.
- Low Pitch: The roar of a lion.
Importantly, pitch should not be confused with loudness, which is determined by the amplitude of the sound wave, referring to how soft or loud a sound is perceived. Thus, the correct answer to the question is: B. how high or how low a sound is.
