Question

In a standing wave all particle vibrate with same amplitude true false

Answer 1

Answer:

The particles with an interval between two consecutive nodes are in phase but the particles in two such consecutive intervals are of opposite phase

Stationary waves:

There are points at regular intervals which are never displaced are called Nodes. And where the particles periodically attain maximum or minimum value are called antinodes.

In Stationary waves,

1. All the particles in the state of vibration except nodes.

2. All the particles between two consecutive nodes have same phase but differ in amplitude.

3. The particles in opposite side of nodes moves in opposite direction hence they are in opposite phase.
