Q: In frequency, the larger the air column, the larger the what?


Read this paragraph and choose the correct option from the provided answers:

a) The water forms the bottom of the tube and thus where the node of the wave will be. Thus the air column is where the sound wave can exist. The larger the air column, the larger the wavelength. Frequency is inversely proportional to wavelength, thus the tube with the smallest air column will have the highest frequency. So the answer is tube C.

 Choices:

- mass

- gravity

- absorption

- wavelength


A:
wavelength
