The lowest frequency standing wave that can be formed on the flagpole if the wave propagation speed in the fiberglass is 27302730 m/s is 253 Hz.Flagpole is a flexible pole planted in concrete that consists of fiberglass. The flagpole consists of a flexible, 2.69-2.69 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.In physics, a standing wave is a wave pattern that stays stationary in one position. For standing waves to exist in a material, it must be an enclosed area with a defined size, such as a string tied to a wall or a flagpole planted in concrete. Also, the standing wave must be created through a vibrating system at specific frequencies.The lowest frequency standing wave that can be formed on the flagpole is given by;Frequency = wave velocity/ (2 x length of the standing wave)Frequency = 2730/(2 x 2.69) = 253 HzTherefore, the lowest frequency standing wave that can be formed on the flagpole if the wave propagation speed in the fiberglass is 27302730 m/s is 253 Hz.
