Question

a ray of lightis incident of the glass surface at a polarsing angle of57 calculate the R. I. of glass

Answer 1

As we know,
n = tan i
n = tan 57°
= 1.539
Hope this helps.

Answer 2

Answer:

Step-by-step explanation:

Apply Brewster's law:-

tan(I)=Refractive index

So, refractive index=tan57=1.53
