Key Stage 5

Meaning

An antinode is a point in a stationary wave pattern where the amplitude is at a maximum.

About Antinodes

• Antinodes occur at positions where constructive interference happens.
• They are the opposite of nodes, where amplitude is zero.
• Found in standing wave patterns in physics, such as on strings or in air columns.

Examples

• The loudest points in a musical instrument's sound wave are antinodes.
• Antinodes can be visualized in vibrating string experiments.
