61. (a) The phasor diagram is shown here: y 1 , y 2 , and y 3 represent the original waves and y m represents the resultant wave. The horizontal component of the resultant is y mh = y 1 y 3 = y 1 y 1 /3 = 2 y 1 /3. The vertical component is y mv = y 2 = y 1 /2. The amplitude of the resultant is 22 11 25 0.83 . 32 6 mm h m v yy y y y §· § · =+ = + = = ¨¸ ¨ ¸ ©¹ © ¹ (b) The phase constant for the resultant is
