MCQ
Two waves of the same frequency and intensity superimpose with each other in opposite phases. Then after superposition the ……
  • A
    intensity increases to four times
  • B
     intensity increase to two times
  • C
     frequency increases to four times
  • ✓
    none of the above
✓

Answer

Correct option: D.
none of the above
none of the above
Hint :
Since the waves are in opposite phases, the resultant intensity will be zero. The frequency remains the same. So, the correct choice is (d).
