(II) What would Brewster's angle be for reflections off the surface of water for light coming from beneath the surface? Compare to the angle for total internal reflection, and to Brewster's angle from above the surface.
Step 1 of 5</p>
Brewster's Law; When an unpolarized light undergoes a refraction from one medium to another, The refracted ray and reflected rays are partially polarized, The incident angle, which makes the polarization of reflected and refracted ray to be perpendicular to each other, is called Brewster's angle
;the Brewster's angle
; the refractive index of the first medium.
; the refractive index of the second medium

For the refraction from water to air, the Brewster's angle is;
The Brewster's angle from water to air is
Step 3 of 5</p>
From snell`s law, we can find the critical angle of total internal reflection from water to air
(if the incident angle is critical angle)
