Overview

Stationary waves are formed when two identical progressive waves travel in opposite directions in a bounded medium. In such waves, some points remain at rest as nodes, while some points vibrate with maximum displacement as antinodes. In air columns, stationary waves explain the sound of organ pipes,

Key Concepts

A bounded medium has definite boundaries

A bounded medium has definite boundaries separated from other media by distinct surfaces. Such a medium vibrates only with certain definite frequencie

A progressive wave reflected from

A progressive wave reflected from a free or open end suffers no phase change. The reflected wave keeps the same displacement pattern as the incident w

A progressive wave reflected from

A progressive wave reflected from a rigid or closed end undergoes a phase change of π or 180 degrees. The displacement is inverted after reflection.

When two identical progressive waves travel

When two identical progressive waves travel in opposite directions with the same speed in a bounded medium, their superposition produces a wave that a

Nodes are points of zero displacement

Nodes are points of zero displacement, while antinodes are points of maximum displacement. In longitudinal stationary waves, pressure and density chan

Learning Objectives

  • Understand how reflection of waves at free and rigid boundaries differs
  • Explain the formation of stationary waves by superposition of two opposite progressive waves
  • Identify nodes and antinodes in stationary waves and state their properties
  • Describe stationary waves in longitudinal media, including pressure and density variations
  • Derive and use the frequency relations for closed and open organ pipes
