Match List-I with List-II:
$$\begin{array}{|l|l|l|l|}\hline & \text{List-I (EM wave)} & & \text{List-II (wavelength range)} \\ \hline \text{A.} & \text{Infra-red} & \text{I.} & < 10^{-3}\ \text{nm} \\ \hline \text{B.} & \text{Ultraviolet} & \text{II.} & 400\ \text{nm to }1\ \text{nm} \\ \hline \text{C.} & \text{X-rays} & \text{III.} & 1\ \text{mm to }700\ \text{nm} \\ \hline \text{D.} & \text{Gamma rays} & \text{IV.} & 1\ \text{nm to }10^{-3}\ \text{nm} \\ \hline \end{array}$$
Choose the correct answer from the options given below:
Answer: (A) (A)-(III), (B)-(II), (C)-(IV), (D)-(I)
- Infrared: $1\ \text{mm}$ to $700\ \text{nm}$ → (III)
- Ultraviolet: $400\ \text{nm}$ to $1\ \text{nm}$ → (II)
- X-rays: $1\ \text{nm}$ to $10^{-3}\ \text{nm}$ → (IV)
- Gamma rays: below $10^{-3}\ \text{nm}$ → (I)
