To find the wavelength of the middle F note on a piano, we can use the formula:
wavelength = speed of sound / frequency
Given that the frequency of the middle F note on a piano is 349.23 Hz, and the speed of sound in air is 343.06 m/s, we can substitute these values into the formula to get:
wavelength = 343.06 / 349.23
wavelength = 0.982 meters (since 1 meter = 100 cm, we can convert this to centimeters by multiplying by 100)
wavelength = 98.2 cm
Therefore, the wavelength of the middle F note on a piano is 98.2 cm.
