Question 2 A sound has a high pitch and a low volume. What is probably true of this sound wave? Your answer: O It has a high frequency, and the amplitude is low because the source is far away. It has a high frequency, and the amplitude is low because close to the observer. O It has a low frequency, and the amplitude is low because the source is far away. It has a low frequency, and the amplitude is low because close to the observer.
