Plane-polarized light of intensity 60 W/m^2 falls on a polarizing filter whose axis is at 37^circ to the plane of polarization. The transmitted intensity is:

  1. 38.3 W/m^2
  2. 76.5 W/m^2
  3. 19.1 W/m^2
  4. 383 W/m^2
Answer

A) 38.3 W/m^2

I = I0cos^2theta = 60cos^2 37^circ = 38.3 W/m^2. SLO P-11-D-06 · Understanding
