Two SHM's are represented by y = a sin (omegat - kx) and y = b cos (omegat - kx) . The phase difference between the two is :

Two SHM's are represented by y = a sin (omegat - kx) and y = b cos (omegat - kx) . The phase difference between the two is :

Two waves y_1 = A sin (omegat - kx) and y_2 = A sin (omegat + kx) superimpose to produce a stationary wave, then

Three one-dimensional mechanical waves in an elastic medium is given as y_1 = 3A sin (omegat - kx), y_2 = A sin (omegat - kx + pi) and y_3 = 2A sin (omegat + kx) are superimposed with each other. The maximum displacement amplitude of the medium particle would be
