A flagpole consists of a flexible, 7.02 m tall fiberglass pole planted in concrete. The bottom end of the flagpole is fixed in position, but the top end of the flagpole is free to move. What is the lowest frequency standing wave that can be formed on the flagpole, if the wave propagation speed in the fiberglass is 2730 m/s?
