Two sinusoidal waves of the same frequency are to be sent in thesame direction along a taut string. One wave has an amplitude of5.0 mm, the other 8.0 mm. (a) What phase difference between the two waves results in the smallest amplitude of the resultant wave? (b) What is that smallest amplitude? (c) What phasedifference resultsin the largest amplitude of the resultant wave? (d) What is thatlargest amplitude? (e) What is the resultant amplitude if the phaseangle is ?
