Write your understanding about coherent waves. A steel wire in a piano has a length of L = 0.9m а. and a mass of m = 5.4 g. To what tension T must this wire be stretched so that its fundamental vibration possess a frequency f= 261.6 Hz? b. The equation of a plane sound wave is, y(x,t) = 6.0 × 10-6 sin(5.7x – 1500t). Find the frequency, the wavelength and the velocity of the wave. Compare the wavelength with the amplitude of the oscillations and the wave velocity with the amplitude of the velocity of the oscillations. What is the phase shift between the oscillations of two points 30.0 cm apart in the direction of the sound wave?
