Ответ:
The wacelength of this note is 87.5 cm
Explanation:
Step 1: Data given
Frequency of the middle G note = 392.00 Hz
The speed of sound in air is 343.06 m/s
Step 2: Calculate the wavelength
The wavelength of a sinusoidal wave travelling at a speed c and frequency f is c/f.
In this case c is the speed of sound of 343.06m/s and the frequency is 392.00 Hz.
So the wavelength would be c/f = 343.06 / 392.00 = 0.875 m
0.875 m = 87.5 cm
The wacelength of this note is 87.5 cm
