2. soun Middle English To call sound d English I vibration that propagates as an aaudible wave of pressure,through t the transmission medium. Physics The reception of such waves & their perception by the brain. a Human physiology & Psychology

3. How is Sound produced Body vibrates Vibration of particles receiver medium The speed of sound depends on the elasticity and density of the medium through which it is traveling. Frequencies of sound waves

4. ANATOMY OF A SIMPLE SOUND WAVE

5. V = f λ

6. The Relation between time period T and its frequency f of a wave

8. Longitudinal wave  medium particles vibrate along the direction of the propagation of the wave  also called compresional or compression waves  Travel in solids,liquids and gases.

9. Transverse wave  The particle displacement is perpendicular to the direction of wave propagation  Forms crests and troughs  Formed only in those media which posses rigidity and hence travels only in solids and liquids

10. Water Waves  Involve a combination of both longitudinal and transverse motions
