M8-04: OPTICAL ACTIVITY IN KARO SYRUP TANK

m8-04am8-04b

 

Additional Info

  • ID Code: M8-04
  • Purpose: Show rotation of the plane of polarization of white light in a uniform tank of Karo syrup.
  • Description: Polarized white light enters the end of the tank of Karo syrup. The light which is scattered out in the horizontal plane so that we can see it, as in the photograph, shows a series of subtractive colors, indicating that some spectral color - the one scattered vertically - is missing. Viewed from the top, one sees a somewhat different sequence of colors which are complementary colors to those viewed in the horizontal plane. This demonstrates that the plane of polarization of the light is rotated by an amount which is dependent on wavelength. The two photographs above are close-ups of the tube with the polaroid aligned vertically and horizontally.
