38.  Light is incident from air onto the surface of a liquid. The angle of incidence is 53.0°, and the angle of refraction is 34.0°. At what angle of incidence would the reflected light be 100% polarized?

 

Brewster’s angle for 100% plane polarized light on reflection is given by

 

Snell’s Law gives us

 

So solve for

 

 

Now we can find the angle of incidence for polarization
