The frequency of sound in air can be calculated using the formula:
Frequency = Speed of Sound / Wavelength
In dry air at 20 degrees Celsius, the approximate speed of sound is around 343 meters per second (m/s).
To convert the wavelength from centimeters (cm) to meters (m), we divide by 100:
Wavelength = 10 cm / 100 = 0.1 m
Now we can substitute the values into the formula:
Frequency = 343 m/s / 0.1 m = 3430 Hz
Therefore, if the wavelength of sound in the air is 10 cm, the frequency would be approximately 3430 Hz (Hertz).
