Question

PLEASE HELP!! Use the information below to solve this problem: A note has a wavelength of 0.65551 m. If the speed of sound is 343.00 m/s, what pitch is this note?

speed of sound in air: 343 m/s

A. 440.00 Hz
B. 493.88 Hz
C. 523.25 Hz
D. 587.33 Hz
E. 659.26 Hz
F. 698.46 Hz
G. 783.99 Hz​

Answer 1

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
