Plane-polarized light of intensity 50 W/m^2 falls on a polarizing filter whose axis is at 0^circ to the plane of polarization. The transmitted intensity is:

  1. 500 W/m^2
  2. 50 W/m^2
  3. 100 W/m^2
  4. 25 W/m^2
Answer

B) 50 W/m^2

I = I0cos^2theta = 50cos^2 0^circ = 50 W/m^2. SLO P-11-D-06 · Understanding
