help me please

Three polarizing filters are stacked with the polarizing axes of the second and third at 53.0degree, respectively, with that of the first. An unpolarized light of intensity I0 is incident on the stack. Find the intensity of light emerging from the first filter. I1 = Find the intensity of light emerging from the second filter. I2 = Find the intensity of light emerging from the third filter. I3 = If the second filter is removed, what is the intensity of the light emerging from the first filter? I1 = I0 Part E If the second filter is removed, what is the intensity of the light emerging from the last filter? I3 = I0

Explanation / Answer

i1=io/2

i2=i1cos[53]^2=0.181 Io

i3=I2 cos[90-53]^2

=0.115 Io

d)I1=Io/2

e)I3=I1 COS90=0
