6. one cycle of a sine wave always has \n\na one positive and one negative alternation \n\nb two positive alternations in succession \n\nc one positive and one negative cycle \n\nd two negative cycles in succession

6. one cycle of a sine wave always has \n\na one positive and one negative alternation \n\nb two positive alternations in succession \n\nc one positive and one negative cycle \n\nd two negative cycles in succession

Answer

Brief Explanations:

A sine - wave is a periodic function. One complete cycle of a sine wave consists of the wave going above the x - axis (positive alternation) and then below the x - axis (negative alternation).

Answer:

A. one positive and one negative alternation
