Answer:
The speed of sound in air at 5°C is approximately 331.4 m/s.
To find the wavelength of a sound wave, we can use the formula:
wavelength = speed of sound / frequency
wavelength = 331.4 / 651
wavelength = 0.509 meters (or 50.9 centimeters)
Therefore, the wavelength of a 651 Hz sound wave in air at 5 degrees Celsius is approximately 0.509 meters.
