Answer:

C

Step-by-step 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
