Question

Physics
need help w part b and c
Light reflected from a horizontal surface, such as a
road or a lake, has a partial horizontal polarization.
We can think of the light as a mixture of horizontally
polarized light and unpolarized light. Suppose the
reflected light from a road surface is 50% polarized
and 50% unpolarized. The light intensity is
220 W/m².
What is the intensity after the light passes through a polarizing filter whose axis makes an angle
from the horizontal of 0°?
Express your answer with the appropriate units.
Io = 170

Follow-up Question

Light reflected from a horizontal surface, such as a road or a lake, has a partial horizontal polarization. We can think of the light as a mixture of horizontally polarized light and unpolarized light. Suppose the reflected light from a road surface is 50%% polarized and 50%% unpolarized. The light intensity is 120 W/m2W/m2.
