MCQ
If the phase difference between the two wave is 2$\pi $ during superposition, then the resultant amplitude is
  • Maximum
  • B
    Minimum
  • C
    Maximum or minimum
  • D
    None of the above

Answer

Correct option: A.
Maximum
a
(a) Phase difference is $2\pi $ means constrictive interference so resultant amplitude will be maximum.
