MCQ
When two waves with same frequency and constant phase difference interfere,
  • A
    There is a gain of energy.
  • B
    There is a loss of energy
  • C
    The energy is redistributed and the distribution changes with time.
  • ✓
    The energy is redistributed and the distribution remains constant in time.
✓

Answer

Correct option: D.
The energy is redistributed and the distribution remains constant in time.
Explanation:
The energy is redistributed due to the presence of interference. However, as the frequency and phase remain constant. the distribution also remains constant With time.
