Linearly polarized light that is oriented along the x-axis andhas intensity I0 is incident on a linearpolarizer (LP1) with transmission axis oriented at an angleθ1=15° clockwise with respect to the x axis.The light then passes through a second linear polarizer (LP2) withtransmission axis oriented at an angle θ2 = 45°counterclockwise relative to the x axis as shown beforepassing through a quarter wave plate. The fast axis of the quarterwave plate is aligned with the y-axis.
1)
What is the intensity of the light after the second linearpolarizer (LP2) but before the quarter wave plate?
I 2 = 0.25 I0
I 2 = 0.467 I0
I 2 = 0.75 I0
I 2 = 0.233 I0
I 2 = 0.7 I0
2)
What is the polarization after the light passes through thequarter wave plate?
Linearly polarized along θ2
Left circularly polarized
Right circularly polarized
3)
Keeping the linear polarizers and quarter wave plate exactly thesame, the incident light is now changed to be unpolarized as shownbelow. What is the intensity of light measured after the quarterwave plate(IQWPIQWP)?
IQWP=IQWP= 0.125 I0I0
IQWP=IQWP= 0.233 I0I0
IQWP=IQWP= 0.5 I0I0
IQWP=IQWP= 0.0583 I0I0
IQWP=IQWP= 0.467 I0
