Homework Statement



When light strikes an air-material interface from the air side, Brewster’s angle is 63°.
What is the critical angle for total internal reflection for light striking the interface from
the material side?


Homework Equations



tanθB=n2/n1

sinθc=n1/n2
(n2 is greater than n1)

The Attempt at a Solution



n1=1.000

tan63=n2/1.000

n2=1.963

sinθc=(1.000/1.963)

θc=31°
