Question
When two waves with same frequency and constant phase difference interfere,
  1. There is a gain of energy.
  2. There is a loss of energy
  3. The energy is redistributed and the distribution changes with time.
  4. The energy is redistributed and the distribution remains constant in time.

Answer

  1. 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.
