Match List - I with List - II.
$$\begin{array}{|l|l|l|l|}\hline & \text{List I} & & \text{List II} \\ \hline \text{(a)} & \text{Source of microwave frequency} & \text{(i)} & \text{Radioactive decay of nucleus} \\ \hline \text{(b)} & \text{Source of infrared frequency} & \text{(ii)} & \text{Magnetron} \\ \hline \text{(c)} & \text{Source of Gamma Rays} & \text{(iii)} & \text{Inner shell electrons} \\ \hline \text{(d)} & \text{Source of X-rays} & \text{(iv)} & \text{Vibration of atoms and molecules} \\ \hline & & \text{(v)} & \text{LASER} \\ \hline & & \text{(vi)} & \text{RC circuit} \\ \hline \end{array}$$
Choose the correct answer from the options given below:
Answer: (D) (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
Microwaves are produced by a magnetron (ii); infrared by vibrations of atoms and molecules (iv); gamma rays by radioactive decay of nuclei (i); X-rays by transitions of inner shell electrons (iii).
