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.
- The distance between consecutive antinodes is half the wavelength of the wave.
- Antinodes are points of maximum energy transfer in the medium.
- In musical instruments, antinodes correspond to the points where the air column or string vibrates most strongly.
- The study of antinodes and nodes is essential in understanding resonance and harmonic frequencies.
