MCQ
In stationary waves
  • A
    Energy is uniformly distributed
  • Energy is minimum at nodes and maximum at antinodes
  • C
    Energy is maximum at nodes and minimum at antinodes
  • D
    Alternating maximum and minimum energy producing at nodes and antinodes

Answer

Correct option: B.
Energy is minimum at nodes and maximum at antinodes
b
In a stationary wave, node is the point where the amplitude always remains zero at all time and antinode is the point where amplitude will be either minimum or maximum at all time.

When amplitude is at its extremum values the energy of the wave will also be maximum. Hence, it will have maximum energy at antinodes, When amplitude is zero, the energy will also be zero and is the least possible value for energy. Hence, it will have minimum energy at nodes.
