Question 14
Original source text (the exact panel preserves diagram labels, tables and choices):
Alex and Bella are playing their guitars together. Alex plays a note with a
frequency of 528 Hz, while Bella plays a note with a frequency of 396 Hz. Bella's
guitar sounds noticeably louder than Alex's. The speed of sound in air is 330 m/s.
Based on this information, which statement is INCORRECT?
A. The pitch of the note played by Alex is higher than that played by Bella.
B. The amplitude of the sound wave from Bella's guitar is greater than that from
Alex's guitar.
C. The period of the sound wave from Alex's guitar is shorter than that from
Bella's guitar.
D. If this experiment were repeated on the Moon, the difference in loudness
would be even more pronounced.
