Question

Match the column $\text{I}$ and column $\text{II}$ correctly.

Column $\text{I}$	Column $\text{II}$
$\left(A\right)$ Interference of light	$\left(p\right)$ $I=I_0{\cos }^2\theta$
$\left(B\right)$ Brewster's law	$(q$) Obstacle/aperature size $\approx \lambda$
$\left(C\right)$ Diffraction of light	$(r$) $\mu =\tan i_p$
$\left(D\right)$ Law of Malus	$\left(s\right)$ Coherent sources

• A. $A-r,B-s,C-q,D-p$
• B. $A-p,B-q,C-r,D-s$
• C. $A-s,B-r,C-p,D-q$
• D. $A-s,B-r,C-q,D-p$

Answer 1

The correct option is D $A-s,B-r,C-q,D-p$

$\left(1\right)$ The sources must be coherent for interference of light to take place.

So, $\left(A\right)$ matches with $\left(s\right)$.

$\left(2\right)$ According to Brewster's law $\mu =\tan i_p$.

So, $\left(B\right)$ matches with $\left(r\right)$.

$\left(3\right)$ Diffraction only occurs when the size of aperture or obstacle is comparable to the wavelength of light.

So, $\left(C\right)$ matches with $\left(q\right)$.

$\left(4\right)$ According to law of malus, $I=I_0{\cos }^2\theta$

So, $\left(D\right)$ matches with $\left(p\right)$.

Hence, option $\left(\text{D}\right)$ is correct.
