    How do you find the angle of polarization? What is the formula? Its not in my physics book and I looked online and couldn't find it.

    Polarization of what? Of some linearly polarized light? Or of a polarizing filter? What is the context of the question?

    the angle of polarization of ethyl alcohol.

    Sorry, I'm still not understanding the question. Are you asking how ethyl alcohol can affect the polarization of light? Are you going to apply an electric field across the ethyl alcohol and measure the birefringence?

    ok the question reads exactly like this
    Find the angle of polarization and the corresponding angle of refraction for ethyl alcohol.
    That is all it says.

    Perhaps you are referring to Brewster's Law?
    You'll need the refractive index of ethanol
