Plane-polarized light of intensity 100 W/m^2 is reduced to 25 W/m^2 by a polarizer. The angle between the polarization plane and the polarizer's axis is:

  1. 75.5^circ
  2. 60^circ
  3. 30^circ
  4. 63^circ
Answer

B) 60^circ

cos^2theta = 25100 Rightarrow theta = 60^circ. SLO P-11-D-06 · Understanding
