Question

angle of incidence is {{60}^{0}}600 and angle of refraction is{{30}^{0}}300, then refractive index of medium is _______.​

Answer 1

From Brewster's law

The refractive index of the medium is given by

n=tani

p

where i

p

= polarising angle

⇒n=tan60

o

⇒n=

3

If C be the critical angle for the medium then,

n=

sinC

1

sinC=

n
