.The wave function on a taut string is y(x,t) = (0.50m)sin(12 л t-3 л x+л/4) where x is in meters and t in seconds.(a)What is the speed and wavelength of the wave?(b)What is the average rate at which energy is transmitted along the string if the linear mass density is 70 g/m? (c)What is the energy contained in each cycle of a wave?
