The wavelength of a sound wave can be calculated using the formula:
wavelength = speed of sound / frequency
Plugging in the values given:
wavelength = 340 m/s / 392 Hz
wavelength = 0.867 meters or approximately 0.87 meters
Therefore, the answer is option A: 0.87 meters.
In music, the note G above middle C has a frequency of about 392 hertz. If the speed of sound in the air is 340 m/s, what is the approximate wavelength of this note?
