6.1 WAVES: INTRODUCTION

WAVES
  • Waves is a periodic motion to transfer energy from the centre of vibration.
  • Waves travel and transfer energy (its amplitude) and information (its frequency) from one point to another, with no permanent displacement of the particles of the medium.
  • The particles of the medium are oscillate around an almost fixed positions.



EXAMPLES OF WAVES










WAVES TRANSFER ENERGY WITHOUT TRANSFERRING MATTER






  • A wave transfers energy and the momentum from the source of the wave (the oscillating or vibrating system) to the surroundings
