If a progressive wave and a stationary wave have frequency 300 Hz and the same wave velocity 360 m/s, then calculate, (i) The phase difference between two points on the progressive wave which are 0.4 m apart. (ii) The equation of motion of progressive wave if its amplitude is 0.02 m (iii) The equation of the stationary wave if its amplitude is 0.01 m (iv) The distance between consecutive nodes in the stationary wave
