Question

These two waves travel along the same string:

y_{1} = (4.57 mm)
sin(2.24πx - 320πt) |

y_{2} = (5.81 mm)
sin(2.24πx - 320πt +
0.800π rad). |

What are **(a)** the amplitude and
**(b)** the phase angle (relative to wave 1) of the
resultant wave? **(c)** If a third wave of amplitude
4.93 mm is also to be sent along the string in the same direction
as the first two waves, what should be its phase angle in order to
maximize the amplitude of the new resultant wave?
