A transverse wave of amplitude 050 mm and frequency 100 Hz is produced on a wire stretched to a tension of 100 N. If the wave speed is 100 m s1, what average power is the source transmitting to the wire?

By the given data, we can interpret that,




We know that average power of the source is determined by,



Here, we got m and v, a, f is given. Putting the values, we obtain the answer to be 49 mW.
