Lab 13 Photos

Lab 13 was to build a Michelson interferometer and obtain first fringes. Both teams were successful, achieving fringes in an hour or less. Here are some photos.

Team A planning their buildup and alignments. The team came up with a perforated card as an alignment aid that was used to ensure the beam was a constant height above the table.

Team B doing their layout. Fringes obtained at t=1 hour using shimmed and hand-touch alignments. Not bad!
