Standing Wave
- Standing waves result from the interference of two waves traveling in opposite directions with the same frequency and amplitude.
- Instead of propagating, the energy of these waves becomes confined within a specific region, forming a stationary pattern of oscillation.
- Standing waves have points of minimal displacement called nodes and points of maximal displacement called antinodes.
- They are observed in various physical systems, including vibrating strings, acoustic resonance in pipes, and electromagnetic waves in transmission lines.
- Standing waves play a crucial role in phenomena such as musical instrument vibrations, sound resonance, and the behavior of electromagnetic fields in antennas.

Introduction to Waves – Definition, Types, Properties
A wave is a propagating dynamic disturbance (change from equilibrium) of one or more quantities in physics, mathematics, and related subjects, commonly described by a wave equation.
At least two field quantities in the wave medium are involved in physical waves. Periodic waves occur when variables oscillate periodically around an equilibrium (resting) value at a specific frequency.
A traveling wave occurs when the entire waveform moves in one direction; a standing wave occurs when two superimposed periodic waves move in opposite directions. The amplitude of vibration in a standing wave features nulls at some points when the wave amplitude seems reduced or even zero.
