Plane-polarized light of intensity 80 W/m^2 is reduced to 60 W/m^2 by a polarizer. The angle between the polarization plane and the polarizer's axis is:

  1. 30^circ
  2. 15^circ
  3. 41.4^circ
  4. 60^circ
Answer

A) 30^circ

cos^2theta = 6080 Rightarrow theta = 30^circ. SLO P-11-D-06 · Understanding
