Answer:
C
Explanation:
Given that a note has a wavelength of 0.65551 m. If the speed of sound is 343.00 m/s, the pitch of the note is the same as the frequency.
Sound Velocity = product of frequency and wavelength.
Substitute wave speed and wavelength into the formula
343 = f × 0.65551
Make f the subject of formula
F = 343 / 0.65551
F = 523.58 Henz
Therefore, the pitch of the note is 523.52 Hz approximately
The correct answer is option C
