Answer & Solution
Correct Answer
(D) (iv) (iii) (i) (ii)
Step-by-step Solution
Detailed explanation
Figure showing the ray diagram of refraction at a plane surface. Given, \(i_p=\) angle of polarisation So, \( i_p=\tan ^{-1} \mu \Rightarrow i_p=\tan ^{-1} \sqrt{2}=\sin ^{-1} \sqrt{\frac{2}{3}} \) From Snell's law, \( \sin i_p=\mu \sin r \) Here,…
