Question:

$\text{Match List-I with List-II and choose the correct option.}$ $\begin{array}{|c|c|} \hline \text{List-I} & \text{List-II} \\ \hline (A) \ \text{Microwave} & (p) \ 400 \ \text{nm} - 1 \ \text{nm} \\ (B) \ \text{Ultraviolet} & (q) \ 1 \ \text{nm} - 1 \ \text{pm} \\ (C) \ \text{X-rays} & (r) \ 2.5 \ \mu\text{m} - 750 \ \text{nm} \\ (D) \ \text{Infrared} & (s) \ 1 \ \text{mm} - 25 \ \mu\text{m} \\ \hline \end{array}$

Options:

1. $\text{A-(s), B-(q), C-(r), D-(p)}$
2. $\text{A-(s), B-(p), C-(q), D-(r)}$
3. $\text{A-(p), B-(s), C-(q), D-(r)}$
4. $\text{A-(r), B-(q), C-(s), D-(p)}$

Solution:

$\text{Hint: Recall the electromagnetic spectrum.}$ $\text{Step: Find the correct wavelength of each wave.}$ $\text{The electromagnetic spectrum is based on wavelength ranges given by:}$ $\text{Microwave: } 1 \ \text{mm} - 25 \ \mu\text{m}$ $\text{Ultraviolet: } 400 \ \text{nm} - 1 \ \text{nm}$ $\text{X-rays: } 1 \ \text{nm} - 1 \ \text{pm}$ $\text{Infrared: } 2.5 \ \mu\text{m} - 750 \ \text{nm}$ $\text{Therefore, the correct match is A-(s), B-(p), C-(q), D-(r).}$ $\text{Hence, option (2) is the correct answer.}$
