A standing wave has no velocity, hence the name.

### Standing waves are produced by the superposition of two waves with

They are stationary and.

Travelling waves transport energy from one area of space to another, whereas standing waves do not transport energy.

The nodes are located at positions x N for which sine is zero: And isolating we get: where n is an integer.

It states that: The wave resulting from the superposition of two or more waves is the sum of the individual waves.

Description: They are called standing waves.

Standing waves in air columns also form nodes and antinodes, but the phase changes involved must be separately examined for the case of air columns.
We are going to find the resultant wave caused by the interference of two harmonic waves of equal amplitude, frequency and wave length moving in opposite directions along a string.
For any fixed x-value, x 0, the equation above gives us the position of only that point of the string against time: which is precisely the equation describing simple harmonic motion.

How will standing waves result from the superposition of two waves? Standing waves are the consequence of the constructive interference of waves that have the same amplitude and frequency but are traveling in opposite directions.

Let us say two waves are travelling alone and the displacements of any element of these two waves can be represented by y 1 (x, t) and y 2 (x, t). When these two waves overlap, the resultant displacement can be given as y(x,t). Mathematically, y (x, t) = y 1 (x, t) + y 2 (x, t)

Standing waves are formed by the superposition of two travelling waves of the same frequency (with the same polarisation and the same amplitude) travelling in opposite directions. This is usually achieved by using a travelling wave and its reflection, which will ensure that the frequency is exactly the same.
