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
(d) the energy is redistributed and the distribution remains constant in time.
digAnsr: d
Ans : (d) the energy is redistributed and the distribution remains constant in time.
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.
