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. θ 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 ↑ |__________|__________|__________|__________|_ → θ 90 180 270 360 (B) Third Polarizer between two Crossed Polarizers First polarizer at 0 , second at 90 , third polarizer between them at angle θ to the first. (B.1) Sketch of observed transmitted intensity as a function of θ Intensity ↑ |__________|__________|__________|__________|_ → θ 90 180 270 360 0 Physics 214 2 (B.2) With the help of a diagram of polarization vectors, explain why light can pass this combination of three polarizers. (B.3) Write an expression of the transmitted intensity as a function of θ . I is the intensity emerging from the first polarizer. What is the maximum possible transmitted intensity?...
