Question: A flagpole consists of a flexible, 2.89 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.
Part A: 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?
Please show me how you solve the above question.
