What phase difference between two identical traveling waves, moving in the same direction along a stretched string, results in t
he combined wave having an amplitude 1.703 times that of the common amplitude of the two combining waves? Express your answer in degrees (no need to write the unit).
Science is based on theories and tests, if someone has a theory they will test and if it is correct yippie! and if it isn't they will redo the test over until they get it correct or unless it is unsolvable.
