Standing waves

• Standing waves are wave patterns where specific points remain stationary (called nodes) while other points oscillate with maximum amplitude (called antinodes).
• STANDING WAVE:

  Key characteristics:

  • Formed by interference of two waves traveling in opposite directions
  • Waves have equal amplitude and frequency
  • No net energy transfer along the wave
  • Appear to "stand still" rather than propagate

  Example:Imagine a guitar string vibrating. When plucked, the string creates a standing wave where some points (nodes) don't move, while others (antinodes) move dramatically up and down.

• RESONANCE:

  The storing of energy in an oscillation or a stationary wave, the energy coming from an external source
