Unformatted text preview: Physics 214 1 UNIT 3 POLARIZATION AND BIREFRINGENCE Name_____________________ Lab Partner(s)__________________ Date__________ Lab Section #_______________ TA signature________________ Be sure to have your TA check your lab work and sign this sheet before you leave. Save it until the end of the semester. You may need it for studying, and it is your record of having done the lab. (A) Malus Law See lab manual for instructions. is the angle with respect to the first polarizer. I is the intensity emerging from the first polarizer. In what way are your observations consistent with Malus Law? Intensity |__________|__________|__________|__________|_ 90 180 270 360 (B) Third Polarizer between two Crossed Polarizers First polarizer at 0 , second at 90 , third polarizer between them at angle to the first.
