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)?

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

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

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

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
