Vertically polarized light that has an intensity of 450 W/m2 is incident on two polarizing filters. The first filter is oriented 30° from the vertical while the second filter is oriented 75° from the vertical. Predict the intensity and polarization of the light that emerges from the second filter. (Assume both angles are measured in the same direction with respect to the vertical.) _________W/m2

Please help! Thanks!

Io=450 W/m2

first filter is orientation= 30°

second filter is orientation=75°

from the Malus law,intensity is

I1=Io/2=450/2=225

I2=I1*cos2()

I2=225*cos2(45)

I2=112.5W/m^2
