Development of Learning Resource Material - Wave Motion

This learning material is prepared for the paper  'Understanding the Discipline of Physical Science  Education' and it is a refrence to the development  of learning resource material.

It includes a chapter in physics of class IX, Wave  motion. Wave motion is associated with the  disturbances that propagate from an inertial state  of rest or equilibrium and attains a significant state  of motion. It moves from one point to the other in  an organised manner.
