A steel rod of length 100 cm is clamped at the middle. The frequency of the fundamental mode for the longitudinal vibrations of the rod is (speed of sound in steel = 5 km s –1 )
Text Solution
Verified by ExpertsThe correct answer is:
C
Here, L = 100cm 
As the rod is clamped at the middle, therefore the middle point is a node. IN the fundamental mode, the antinode is formed at each end as shown in figure.
Therefore, the distance two consecutive antinodes = L =1m
