A thin 1.7-m metal rod sustanins a longitudinal standing wave with vibration antinodes at each end of the rod. There are no other antinodes. The density and Young's modulus of this metal are, respectively, 5800 kg/m3 and 5.1x1010 N/m2. What is the frequency of the rod's vibration? Rounded to two significant figures.
