## What is an Antinode?

An antinode is simply a point along a medium which undergoes maximum displacement above and below the rest position.

### What is an Antinode in a wave?

Antinodes are points on a stationary wave that oscillate with maximum amplitude. Nodes are points of zero amplitude and appear to be fixed.

How does tension affect number of antinodes?

On increasing tension in the string, number of anti nodes will be decreasing.

What is tension of a wave?

In physics, tension is described as the pulling force transmitted axially by the means of a string, a cable, chain, or similar object, or by each end of a rod, truss member, or similar three-dimensional object; tension might also be described as the action-reaction pair of forces acting at each end of said elements.

## What is the difference between nodes and antinodes?

A node is a point along a standing wave where the wave has minimum amplitude. For instance, in a vibrating guitar string, the ends of the string are nodes. The opposite of a node is an anti-node, a point where the amplitude of the standing wave is at maximum. These occur midway between the nodes.

### What happens to the wavelength as you increase the tension?

The fundamental wavelength is fixed by the length of the string. Increasing the tension increases the wave speed so the frequency increases.

What is tension the force?

A tension is a force along the length of a medium, especially a force carried by a flexible medium, such as a rope or cable. Note that the rope pulls with equal force but in opposite directions on the hand and the supported mass (neglecting the weight of the rope). This is an example of Newton’s third law.

What is the space between two nodes called?

…the stem is called a node, and the region between successive nodes is called an internode.

## What is the distance between two consecutive antinodes?

In a given stationary wave, the distance between any given two successive nodes or any two successive antinodes is always half of the wavelength.

### Which is the opposite of a node an antinode?

In a sense, these points are the opposite of nodes, and so they are called antinodes. A standing wave pattern always consists of an alternating pattern of nodes and antinodes. The animation shown above depicts a rope vibrating with a standing wave pattern. The nodes and antinodes are labeled on the diagram.

Can a standing wave be an antinode or a node?

Since a standing wave is not technically a wave, an antinode is not technically a point on a wave. The nodes and antinodes are merely unique points on the medium that make up the wave pattern. Watch It! A physics instructor demonstrates and explains the formation of a longitudinal standing wave in a spring.

What causes the pole to break at the antinode?

It is understood that flexural waves generated in the pole would cause it to break at the antinode, where the curvature is maximum. A maximum signal, therefore, indicates a pressure antinode (a displacement node) and a minimum signal indicates a pressure node (a displacement antinode ).

## How are nodes and anti-nodes formed in physics?

Nodes and Anti-nodes. It is formed as the result of the perfectly timed interference of two waves passing through the same medium. A standing wave pattern is not actually a wave; rather it is the pattern resulting from the presence of two waves of the same frequency with different directions of travel within the same medium.
