A granite rod of 60 cm length is clamped at its middle point and is set into longitudinal vibrations. The density of granite is 
and its Young's modulus is 
. What will be the fundamental frequency of the longitudinal vibrations?
Text Solution
Verified by ExpertsThe correct answer is:
A
Velocity of wave, 
Since, rod is clamped at the middle, shape of fundamental wave is as shown in the figure. A represents the antinodes.
As, 
So, fundamental frequency is
