Two mechanical waves intersect and produce the straight line seen here. What must be true about the amplitude of both waves? A) They are equal. B) They are summative. C) They are equal and opposite. D) The blue wave transfers more energy than the red wave.

Respuesta :


They are equal and opposite.

Answer : The amplitude of both waves should be equal and opposite.

Explanation :

In this case, two mechanical waves intersect and produce the straight line seen here. This shows the resultant wave has amplitude equals to zero. Hence, the destructive interference occurs.

The amplitude of both waves should be equal and in opposite direction in order to make resultant equal to zero.

Hence, the correct option is (C) "they are equal and opposite."
