A simple harmonic progressive wave is incident normally on a reflecting surface and gets reflected normally back with the reflected amplitude 80% of the incident one. When the incident wave and the reflected one get superposed, there will be

  • (A):no energy transfer along the path of superposition
  • (B):energy transfer towards the reflecting surface only
  • (C):energy transfer away from the reflecting surface only
  • (D):positions of maximum and minimum amplitudes alternately on the path of the superposition.

Best Answer

Correct Answer:

(D): positions of maximum and minimum amplitudes alternately on the path of the superposition.
