Two sinusoidal wave of the same frequency are to be sent in the same direction along a taut string. One wave has an amplitude of `5.0 mm`, the other `8.0 mm`. (a) What phase difference `phi_(1)` between the two waves results in the smallest amplitude of the resultant wave? (b) What is that smallest amplitude? (c) What phase difference `phi_(2)` results in the largest amplitude of the resultant wave ? (d) What is that largest amplitude? (e) What is resultant amplitude if the phase angle is `(phi_(1) - phi_(2))//2`?
