A long string held by two men, one on each end. Man A oscillates the end that hold producing a wave described by a function y,(x, t) = A sin(kx-ut) and student B oscillates the string producing at twice the frequency, moving in the opposite direction. Both waves move at the same speed v= uk. The two waves interfere to form a resulting wave whose wave function is y (x, t) = y, (x, t) + y, (x, t). Find the velocity of the resulting wave using the linear wave equation dx² dr²
