# A report onStanding wave

Wave that oscillates in time but whose peak amplitude profile does not move in space.

- Standing wave

## Wave

Propagating dynamic disturbance of one or more quantities.

Propagating dynamic disturbance of one or more quantities.

When the entire waveform moves in one direction, it is said to be a traveling wave; by contrast, a pair of superimposed periodic waves traveling in opposite directions makes a standing wave.

## Resonance

Applied 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.

## Node (physics)

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

## Resonator

Device or system that exhibits resonance or resonant behavior.

Device or system that exhibits resonance or resonant behavior.

The oppositely moving waves interfere with each other, and at its resonant frequencies reinforce each other to create a pattern of standing waves in the resonator.

## Hydraulic jump

Phenomenon in the science of hydraulics which is frequently observed in open channel flow such as rivers and spillways.

Phenomenon in the science of hydraulics which is frequently observed in open channel flow such as rivers and spillways.

When this occurs, the water slows in a rather abrupt rise (a step or standing wave) on the liquid surface.

## River surfing

River surfing is the sport of surfing either standing waves, tidal bores or upstream waves in rivers.

## Optical cavity

An optical cavity, resonating cavity or optical resonator is an arrangement of mirrors that forms a standing wave cavity resonator for light waves.

## Standing wave ratio

Measure 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.
