# A report on Standing wave and Node (physics)

A node is a point along a standing wave where the wave has minimum amplitude.

- Node (physics)The locations at which the absolute value of the amplitude is minimum are called nodes, and the locations where the absolute value of the amplitude is maximum are called antinodes.

## Standing wave ratio

0 linksMeasure of impedance matching of loads to the characteristic impedance of a transmission line or waveguide.

Measure of impedance matching of loads to the characteristic impedance of a transmission line or waveguide.

Impedance mismatches result in standing waves along the transmission line, and SWR is defined as the ratio of the partial standing wave's amplitude at an antinode (maximum) to the amplitude at a node (minimum) along the line.

## Resonance

0 linksApplied periodic force is equal or close to a natural frequency of the system on which it acts.

Applied periodic force is equal or close to a natural frequency of the system on which it acts.

In many cases these systems have the potential to resonate at certain frequencies, forming standing waves with large-amplitude oscillations at fixed positions.

At fixed positions called nodes, the string is never displaced.
