A transverse wave of amplitude 0.50 mm and frequency 100 Hz is produced on a wire stretched to a tension of 100 N. If the wave speed is 100 ms−1, what average power is the source transmitting to the wire ?
A tuning fork of frequency 440 Hz is attached to a long string of linear mass density 0.01 kg m−1 kept under a tension of 49 N. The fork produces transverse waves of amplitude 0.50 mm on the string. (a) Find the wave speed and the wavelength of the waves. (b) Find the maximum speed and acceleration of a particle of the string. (c) At what average rate is the tuning fork tranmitting energy to the string ?
