Transcript

  • 1. Wave propertiesWavefront – a line joiningpoints that are in phase - the lines you seewhen ripples spread onwater are wavefronts Rays – arrows drawn to show the direction of wave motion
  • 2. Reflection- The bouncing ofwaves off a surfaceRegular reflection –reflection from a smoothsurface - an image wouldappear to be coming frombehind the surface
  • 3. Diffuse reflection –reflection from a non-smooth surface - light bounces offthe surface but no imagecan be seenWhen light hits a surface, part of the wave is reflected,part is absorbed by the atoms of the material.When light hits a transparent material, some istransmitted through the window.
  • 4. Law of reflectionThe angle of incidence equals theangle of reflectionAll angles are measured to thenormal line (perpendicular to thesurface)
  • 5. RefractionWhen a wave passes from one medium intoanother, its velocity changes. If the wave hits theboundary at an angle, the wave also changesdirection.
  • 6. Light travels at 2 x 108 m/s in a substance. What is itsindex of refraction?The index of refraction of a liquid is 0.80. How fastdoes light travel in it?
  • 7. Snell’s Law
  • 8. A water wave travelling at 20 m/s enters a shallowregion where its velocity is 15 m/s. If the angle ofincidence of the water wave is 50o, what is theangle of refraction?35.2o
  • 9. Light travelling through air is incident on thesurface of a pool of water at an angle of 40o.Calculate the angle of refraction.
