# Explain the Formation of Stationary Wave by Analytical Method. Show that Nodes and Antinodes Are Equally Spaced in a Stationary Wave. - HSC Science (Electronics) 12th Board Exam - Physics

#### Question

Explain the formation of stationary wave by analytical method. Show that nodes and antinodes are equally spaced in a stationary wave.

#### Solution

Formation of stationary waves by analytical method:

1) Consider two identical progressive waves of equal amplitude and frequency travelling along X axis in opposite direction. They are given by,

Thus, distance between two successive antinodes is λ/2.
Hence, nodes and antinodes are equispaced. The distance between a node and an adjacent antinode is lambda/4
