The wave can be defined as the disturbance traveling in a medium due to the vibratory motion of medium by virtue of elasticity and inertia.
Types of waves:
Transverse waves:- In these waves, the particles of medium vibrate perpendicular to the direction of propagation of waves.
Longitudinal waves:- In these waves, the particles of medium vibrate parallel or anti parallel to the direction of propagation of waves.
Progressive or Traveling:- If there is a continuous transfer of energy in one direction across any cross-section of the medium, the waves are called progressive or traveling.
Stationary or Standing:- If the net transfer of energy across any cross-section of the medium is zero, the waves are called stationary or standing waves.
