    A. The index of refraction of a glass plate is 1.5. What is Brewsters angle when the plate is in the air?
    (n air=1.00)?

    Answer in degrees

    B. What is Brewsters Angle when the plate is in water? (n water=1.33).

    Answer in degrees.

    I went for a meal at a Brewsters once. Terrible food.

    Not sure about the answer to your question though

    Brewsters law
    n=tan b
    where
    n= refractive index of 1st medium w.r.t. 2 medium
    b= Brewster angle
    in the A case
    medium 1 is air & medium 2 is water
    n=n2/n1=1.5/1.0=1.5
    1.5=tan b
    Answer=56.3 deg

    in case B
    medium 1 is water & medium 2 is glass
    therefore
    n=n2/n1=1.5/1.33=1.127
    n=tan b
    1.127=tan b
    b=48.41 deg
    answer is 48.41 deg
