9. Polarization

10. Types of waves  Based on its direction : longitudinal waves and transverse waves  Based on its medium : mechanical waves and electromagnetic waves  Based on its amplitude : standing waves and travelling waves

11. Transverse waves In a transverse wave the oscilation are perpendicular to the direction of motion of the wave Example : the wave along a stretched string

12. Longitudinal waves In a longitudinal wave, the vibrations are parallel to the line of motion of the wave Example : sound wave and slinki wave

14. Progressive waves A progressive wave is one in which the wave profile carries energy and momentum away from the source of disturbance Example : longitudinal wave and transverse wave

16. Velocity of waves Acceleration of waves

17. ANGLE OF PHASE, PHASE AND PHASE DIFFERENCE ANGLE OF PHASE PHASE PHASE DIFFERENCE

18. Stationary waves A stationary wave is formed when two waves of the same frequency and amplitude travelling in opposite directions, are superimposed example : stationary waves on vibrating wires ( Melde’s experiment)
