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:
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
at a particular frequency and sound is produced.
This phenomenon is called
(1) diffraction (3) resonance
(2) refraction (4) the Doppler effect
Answer:
resonance
Explanation:
Resonance is when the frequency matches another objects natural frequency causing it to vibrate.
Answer:
See below
Explanation:
Distance = 27 + 13 = 40 km
Displacement = 27 - 13 = 14 km
