Question
1. A linearly polarized beam of light with the plane of polarization parallel to the vertical reference direction is incident from the left on the first disk with intensity Ii = 10.5 units (arbitrary). Calculate the transmitted intensity after the first polarizer when ?1 = 19.9°. Do not enter units.
2. Calculate the transmitted intensity after the second polarizer when ?2 = 42.0°. Do not enter units.
3. Calculate the transmitted intensity after the third polarizer when ?3 = 61.0°. Do not enter units.
Explanation / Answer
intensity I=I0cos^29theta)
1.I1=10.5*cos^2(19.9)=9.283
2) I2=9.283*cos^2(42)=5.1266
3) I3=5.1266*cos^2(61)=1.2049
