Nano pbl need to know

  1. 1. LASERLight Amplification by the Stimulated Emission ofRadiationMonochromatic (one color) coherent (same frequency, inphase) light
  2. 2. Interference and diffractionLight falling on two slits will produce aninterference pattern(Young’s two-slit experiment)
  3. 3. Interference and diffractionLight falling on two slits will produce aninterference pattern(Young’s two-slit experiment)
  4. 4. x / L = /dλx = how far apart (bright spots) areL = distance from slits to screend = distance between slits, wires on a mesh,tracking grooves on a CD, thickness of ahuman hairUsing a set distance from the wall (L),measure the distance between dots (x) andcalculate d
  5. 5. RubricTeamwork 20Wire mesh Brief description of experiment 5 Data and calculations 10 Sketch of dot pattern 5CD Brief description of experiment 5 Data and calculations 10 Sketch of dot pattern 5Human hair Brief description of experiment 5 Data and calculations 10 Sketch of dot pattern 5ConclusionSummary of overall results 10Visually pleasing, includes photos and/or pictures 10
