Question : 1 of 6
Marks: +1, -0
SECTION -A
When unpolarised light is incident on the interface separating the rarer medium and the denser medium, Brewster angle is found to be 60∘60^{\circ} . Determine the refractive index of the denser medium.
Solution:  
  μ=tan⁡ip\;\mu=\tan i_p
  ip=60∘\;i_p=60^{\circ}
  μ=tan⁡60∘=3\;\mu=\tan 60^{\circ}=\sqrt{3}
