​

Answer 1

${\huge{\bold{\purple{\underline{Answer-}}}}}$

When the angle of incidence on a material is 60∘, the reflected light is completely polarised. The velocity of the refracted ray inside the materials is (in m//sec^(-1)) =v=c√3=3×108√3=√3×108m/sec.

Answer 2

based on Brewster 's law

ų=tani i

i=60

ų=c/v
