Presentation Transcript

  1. Wave Model

  2. Wave Model: Light can be thought of as a wave. Experiments that support this model are reflection, diffraction, and interference.

  3. Particle Model

  4. Particle Model: Light can be thought of as a particle. Experiments that support this are the double-slit experiment, reflection, and photoelectric effect.

  5. Constructive Interference

  6. Constructive Interference: When two waves meet and both have a + or - amplitude at that point in time build up where they overlap.

  7. Destructive Interference

  8. Destructive Interference: When two waves meet and have amplitudes on opposite sides (one + one -) which cancels some or all of both waves.

  9. Photoelectric Effect

  10. Photoelectric Effect: The emission (releasing) of electrons when light hits the surface of an object, most often a piece of metal.

  11. Trough

  12. Trough: The lowest most point on a transverse wave.

  13. Resonance

  14. Resonance: When an object experiences a wave with a frequency that matches its natural frequencywhich can increase the amplitude of the wave in the object.

  15. Photon

  16. Photon: A packet of energy carried in waves.

  17. Electromagnetic Radiation

  18. Electromagnetic Radiation:A kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously.

  19. Diffraction

  20. Diffraction: The process by which a beam of light or other waves is spread out as a result of passing through a narrow opening, typically accompanied by interference.

  21. Crest

  22. Crest: The highest point in a transverse wave.

  23. Double-Slit Experiment

  24. Double-Slit Experiment: An experiment that shows that light can be both a particle and a wave.

  25. Wave-Particle Duality

  26. Wave-Particle Duality: Particles that are very VERY small, like electrons, can behave like a wave and a particle.
