## What is the distance between two nodes?

Distance between two nodes is defined as the number of edges in shortest path from one node from other.

For example, consider below binary tree.

The distance between node 7 and node 6 is 3.

This problem is a standard application of lowest common ancestor of given nodes..

## What is meant by a standing wave?

Standing wave, also called stationary wave, combination of two waves moving in opposite directions, each having the same amplitude and frequency. The phenomenon is the result of interference; that is, when waves are superimposed, their energies are either added together or canceled out.

## How do you find the shortest path in a weighted graph?

Given a directed graph where every edge has weight as either 1 or 2, find the shortest path from a given source vertex ‘s’ to a given destination vertex ‘t’. Expected time complexity is O(V+E). A Simple Solution is to use Dijkstra’s shortest path algorithm, we can get a shortest path in O(E + VLogV) time.

## How do you find the wavelength of a node?

If you know the distance between nodes and antinodes, or if you know the length of string (or pipe length) and which harmonic is present. If you know the distance between nodes and antinodes then use this equation: λ2=D. Where D is the distance between adjacent nodes or antinodes.

## What is the distance between a node and adjacent Antinode?

Hence the distance between a node and its adjacent antinode is 4λ.

## How many nodes does a standing wave have?

two nodesThis standing wave is called the fundamental frequency, with L = λ 2 L= \dfrac{\lambda}{2} L=2λL, equals, start fraction, lambda, divided by, 2, end fraction, and there are two nodes and one antinode.

## What is a node and mode in vibration?

A node is a point along a standing wave where the wave has minimum amplitude. … The opposite of a node is an anti-node, a point where the amplitude of the standing wave is at maximum.

## Are nodes in phase?

Adjacent points are in phase with each other (sections of the wave flap up and down together), so that points of a particular phase remain at a fixed location as time progresses. … Antinodes are points on a stationary wave that oscillate with maximum amplitude. Nodes are points of zero amplitude and appear to be fixed.

## Is the distance between two adjacent Antinodes?

(4) The distance between two adjacent nodes or two adjacent antinodes is equal to half of the wavelength (Figure 5). (5) As the displacement of the nodes is always zero, the waveform is not travelling. Hence energy is confined between two adjacent nodes.

## What is the distance between two nodes of a standing wave?

In a stationary wave, the distance between two successive nodes(anti-nodes) is one half wavelength. Therefore, the distance between a node and the immediate next anti-node is one fourth of a wavelength.

## What is the wavelength of a standing wave?

The waves will all have a frequency of 120 Hz. Their wavelength is given by λ = v/f. Since the frequency is fixed, the wavelength of the waves can only be changed by changing the speed of the waves.

## Is sound louder at node or Antinode?

Where will a man hear the loud sound – at node or antinode? Explain. Sound is produced due to variation of pressure and it is louder where pressure variation is maximum. The strain is maximum at nodes and hence the pressure, therefore the sound is louder at nodes.

## What is horizontal distance in binary tree?

The bottom view of a binary tree refers to the bottommost nodes present at their horizontal distance. For the nodes of a binary tree, the horizontal distance is defined as follows: Horizontal distance of the root = 0. Horizontal distance of a left child = horizontal distance of its parent – 1.

## What do we call the distance between two consecutive compressions of a sound wave?

wavelengthWhat is the term used for the distance between two consecutive compressions or rarefactions called? The distance between two consecutive compressions or rarefactions in a wave is called the wavelength.

## What is the difference between Antinode and node?

These points, sometimes described as points of no displacement, are referred to as nodes. There are other points along the medium that undergo vibrations between a large positive and large negative displacement. … In a sense, these points are the opposite of nodes, and so they are called antinodes.

## What is the meaning of Antinode?

: a region of maximum amplitude situated between adjacent nodes in a vibrating body.

## Whats is a node?

A node is a basic unit of a data structure, such as a linked list or tree data structure. Nodes contain data and also may link to other nodes. Links between nodes are often implemented by pointers.

## How Hadoop determined the distance between two nodes?

The distance between two nodes in the tree plays a vital role in forming a Hadoop cluster and is defined by the network topology and Java interface DNStoSwitchMapping. The distance is equal to the sum of the distance to the closest common ancestor of both the nodes.
