Match List - I with List - II
$$\begin{array}{|l|l|l|l|}\hline & \text{List - I} & & \text{List - II} \\ \hline \text{(a)} & \text{Ultraviolet rays} & \text{(i)} & \text{Study crystal structure} \\ \hline \text{(b)} & \text{Microwaves} & \text{(ii)} & \text{Greenhouse effect} \\ \hline \text{(c)} & \text{Infrared waves} & \text{(iii)} & \text{Sterilizing surgical instrument} \\ \hline \text{(d)} & \text{X-rays} & \text{(iv)} & \text{Radar system} \\ \hline \end{array}$$
Choose the correct answer from the options given below :
Answer: (A) (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)
Ultraviolet rays kill germs, so they are used to sterilise surgical instruments: (a)-(iii).
Microwaves are used in radar: (b)-(iv).
Infrared radiation trapped by the atmosphere causes the greenhouse effect: (c)-(ii).
X-ray diffraction is used to study crystal structure: (d)-(i).
