Question

The angle of incidena of a light beam in air onto
reflecting surface is continously varied. The reflected
vay
found to be completedy polarized when the angle
of incidence is 48
: What is the index of retraction of the reflecting material? ​

Answer 1

Answer:

n=1.00

reflecting off a surface of Index n

Tantheta =n^2 /n^1= n/1.00=n

n=tan thetha = tan (48.0°)=1.11
