I1-14: THERMAL EXPANSION OF ALUMINUM - OPTICAL LEVER

i1-14a

Additional Info

  • ID Code: I1-14
  • Purpose: Demonstrate thermal expansion in a complicated way.
  • Description: A small mirror with an iron lever attached to it rests on one end of an aluminum tube. The other edge of the lever rests on the pole of a magnet. When the aluminum tube is heated with a burner the mirror is deflected. To measure this deflection a laser beam is reflected off the mirror onto a scale as shown in the picture. When the tube is heated the laser spot is deflected about 50 cm when the distance between the mirror and the scale is about 2 m. The picture at the right is a detail of the mirror mount.
  • Availability: Available
  • Loc codes: I1, I0
