Question:

$\text{Match Column I with Column II.}$ $\begin{array}{|c|c|} \hline \text{Column I} & \text{Column II} \\ \hline (a) \text{ Source of microwave frequency} & (i) \text{ Radioactive decay on the nucleus} \\ (b) \text{ Source of infrared frequency} & (ii) \text{ Magnetron} \\ (c) \text{ Source of Gamma Rays} & (iii) \text{ Inner shell electrons} \\ (d) \text{ Source of X-Rays} & (iv) \text{ Vibration of atoms and molecules} \\ \hline \end{array}$ $\text{Choose the correct answer from the options given below:}$

Options:

1. $(a)-(iii), (b)-(ii), (c)-(iv), (d)-(i)$
2. $(a)-(vi), (b)-(i), (c)-(iii), (d)-(ii)$
3. $(a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)$
4. $(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)$

Solution:

$\text{Hint: Gamma rays are emitted in the radioactive decay of the nucleus.}$ $1. \text{ Source of microwave frequency is magnetron.}$ $2. \text{ Source of infrared frequency is vibration of atoms and molecules.}$ $3. \text{ Source of Gamma rays is radioactive decay of nucleus}$ $4. \text{ Source of X-rays inner shell electron transition.}$
