L4-31 DISAPPEARANCE OF GLASS IN LIQUID

Additional Info

  • ID Code: L4-31
  • Purpose: Demonstrates how index of refraction affects what wesee in a fluid bath
  • Description: Glass seems to disappear when immersed in a liquid with the same index of refraction. The bottles, left to right, contain air, water, and two with microscope immersion oil, a liquid with almost the same index of refraction as glass. In the immersion oil, the glass shaft is almost invisible! An air bubble moving up and down in the shaft takes on an odd appearance, as it will be constrained by the shaft but will appear to be moving in free space.

    A video camera is optionally available to make this more visible in large lecture halls.
