Answer:
[tex]0.5I_0[/tex]
Step-by-step explanation:
For polarized light, the intensity of the light transmitted through a polarizer filter is given by Malus' Law:
[tex]I=I_0 cos^2 \theta[/tex]
where:
[tex]I_0[/tex] is the original intensity of the light before the filter
[tex]I[/tex] is the intensity of the light after the filter
[tex]\theta[/tex] is the angle between the direction of polarization of the light and the direction of the axis of the polarizer filter
In this problem, we have:
[tex]I_0[/tex] is the initial intensity of the polarized light
[tex]\theta=45^{\circ}[/tex] is the angle between the axis of the filter and the direction of polarization of the light
Substituting, we find the intensity of the transmitted light:
[tex]I=I_0 cos^2 45^{\circ} = 0.5I_0[/tex]
