  1. WAVES By Hieronimus Fredy Sestywan

  2. Waves Waves is the movement of oscilation Water wave Vibration of SHM

  3. Shape of wave

  4. Properties of waves • Reflection • Refraction • Diffraction • Interference • Polarization

  5. Reflection

  6. Refraction

  7. Diffraction

  8. Interference

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

  12. Movie

  13. 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

  14. Velocity of waves Acceleration of waves

  15. ANGLE OF PHASE, PHASE AND PHASE DIFFERENCE ANGLE OF PHASE PHASE PHASE DIFFERENCE

  16. 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)

  17. Equation of stationary waves on tied end

  18. Superposition of two waves

  19. ANTINODES NODES

  20. Picture of tied end

  21. Stationary waves on free end

  22. SUPERPOSITION OF TWO WAVES

  23. ANTINODES NODES

  24. Picture of free end

  25. VELOCITY OF WAVES BASED ON THE MEDIUM ON STRING ON WATER ON AIR ON SOLID

  26. Movie Standing waves and Progressive waves

  27. General equation of wave

  28. General equation of wave V = f x λ (waves velocity) E = ½ kA2 = 2π2f2mA2 = ½ mω2A2 (energy) I = 2 π2ρvf2A2 (waves intensity)

  29. Doppler effect
