Characteristics of Stationary Waves - QS Study

Some Characteristics of stationary waves

• The waveform remains stationary.
• Nodes and antinodes are formed alternately.
• The points where displacement is zero are called nodes and the points where the displacement is maximum are called antinodes.
• Pressure changes are maximum at nodes and minimum at antinodes.
• All the particles except those at the nodes, execute simple harmonic motions of the same period.
• The amplitude of each particle is not the same, it is maximum at antinodes decreases gradually and is zero at the nodes.
• The velocity of the particles at the nodes is zero. It increases gradually and is maximum at the antinodes.
• The distance between any two consecutive nodes or antinodes is A equal to λ/2, whereas the distance between a node and its adjacent antinode is equal to λ/4.
• There is no transfer of energy. All the particles of the medium pass through their mean position simultaneously twice during each vibration.
• Particles in the same segment vibrate in the same phase and between the neighbouring segments, the particles vibrate in opposite phase.
