Mark out the correct statement(s) regarding waves.A. standing waves appear to be stationary but transfer of energy from one particle to another continues to take place.B. A standing wave not only appears to be stationary but net transfer of energy from one particle to the other is also equal to zero.C. A standing wave does not appear to be stationary and net transfer of energy from one particle to the other is also non - zero.D. A standing wave does not appear to be stationary , but net transfer of energy from one particle to the other is zero. |

Answer» Correct Answer - B Standing waves from two waves of equal amplitude , same frequency , same wavelength travelling in opposite directions superimose , as a result , the net transfer of energy through any cross - section is zero in standing waves. |
