What characterizes the particles located at antinodes in a wave pattern?

  1. They experience no movement

  2. They have maximum displacement

  3. They are at a higher energy state

  4. They exhibit net particle movement towards nodes

The correct answer is: They have maximum displacement

The particles located at antinodes in a wave pattern are characterized by having maximum displacement. In the context of standing waves, antinodes are the points where the amplitude of the wave is at its peak, resulting in the greatest movement of the particles. This means that at antinodes, the particles oscillate between their maximum positive and maximum negative positions, leading to noticeable movement. Understanding this concept is essential in wave physics, as it illustrates how energy is distributed in a wave. At the antinodes, more energy is present compared to nodes, where displacement is minimal, resulting in stillness. As such, focusing on the behavior of particles at these key points helps in analyzing wave phenomena, such as in musical instruments or vibrating strings.
