Definition

1. Noun:
   • A stationary wave pattern: A "standing wave" is a wave pattern that remains in a constant position. This occurs when two waves of identical frequency and amplitude travel in opposite directions and interfere with each other.
   • Characterized by nodes and antinodes: The pattern features points with no vibration (nodes) and points with maximum vibration (antinodes).

Usage Examples

• Noun:
  • The physicist demonstrated a standing wave on a vibrating string.
  • Standing waves can form in musical instruments, such as in the air column of a flute.
  • The experiment showed a clear standing wave pattern in the ripple tank.

Advanced Usage

• "to form a standing wave": describes the creation of this wave pattern.
  • When the frequency is just right, the waves reflect and superimpose to form a standing wave.
• "standing wave pattern": refers to the specific visual or measurable arrangement of nodes and antinodes.
  • The standing wave pattern on the oscilloscope screen was very stable.

Variants and Related Words

• Stationary wave (n): A synonym for "standing wave".
  • A stationary wave is also known as a standing wave.
• Node (n): A point of minimum or zero amplitude in a standing wave.
  • The string is fixed at the nodes.
• Antinode (n): A point of maximum amplitude in a standing wave.
  • The antinode is where the displacement is greatest.

Synonyms

• Stationary wave: A wave that does not appear to travel.

Related Phrases

• Standing wave ratio (SWR) (n phrase): A measure of impedance matching in radio frequency systems, related to the reflection that creates standing waves.
  • A high standing wave ratio indicates poor impedance matching.

Noun

1. a wave (as a sound wave in a chamber or an electromagnetic wave in a transmission line) in which the ratio of its instantaneous amplitude at one point to that at any other point does not vary with time
