- Question Answer
- Two identical piano wires kept under the same tension T have a fundamental frequency
. Two identical piano wires kept under the same tension T have a fundamental frequency
of 600 Hz. The fractional increase in the tension of one of the wires which will lead to occurrence of 6 beats/s when both the wires oscillate together would be
The fundamental frequency of the pianos is given by:
Thus, the fractional change in the frequency is given by:
Hence, option A is correct.
