Question

Match Column I and Column II.

Column I	Column II
(i) Interference	(P) Coherent sources
(ii) Brewster's Law	(Q) $\mu =\frac{1}{\sin C}$
(iii) Malus Law	(R) $\mu =\tan {\theta }_p$
(iv) Total Internal reflection	(S) $I=I_0{\cos }^2\theta$

• A. i $\to$P, ii$\to$ S, iii$\to$ R, iv$\to$ Q
• B. i$\to$ P, ii$\to$R, iii$\to$S, iv$\to$ Q
• C. i$\to$Q, ii$\to$S, iii$\to$R, iv$\to$ P
• D. ii$\to$ R, ii$\to$ R, iii$\to$S, iv$\to$ P

Answer 1

The correct option is B i$\to$ P, ii$\to$R, iii$\to$S, iv$\to$ Q

We know that interference of light waves is only possible when the two sources of light are coherent.
Brewster's law $\mu =\tan {\theta }_p$
Malus law $I=I_o{\cos }^2\theta$
Total internal reflection $\mu =\frac{1}{\sin C}$
So, correct answer is option B.
