(b) 15% of the incident intensity? . . . At what angle should the axes of two Polaroids be placed so as to reduce the intensity of the incident unpolarized light to (a) 32% of the incident intensity?
(b) 15% of the incident intensity? . . . At what angle should the axes of two Polaroids be placed so as to reduce the intensity of the incident unpolarized light to (a) 32% of the incident intensity?
(b) 15% of the incident intensity? (a) 32% of the incident intensity?
(b) 15% of the incident intensity?
Explanation / Answer
. At what angle should the axes of two Polaroids be placed so as to reduce the intensity of the incident unpolarized light to (a) 32% of the incident intensity? I=0.32I0=I0*cosalpha^2/2. so alpha=36.8(degrees) (b) 15% of the incident intensity? I=0.15*I0=I0*cos(alpha)^2/2 so alpha=56.8(degrees)
