Which of the following is not an electromagnetic wave?

Write a short note on light.

$(i)$ The wavelength of microwaves is greater than that of $UV$-rays.
$(ii)$ The wavelength of $IR$ rays is less than that of $UV$-rays.
$(iii)$ The wavelength of microwaves is lesser than that of $IR$ rays.
$(iv)$ Gamma rays have the shortest wavelength in the electromagnetic spectrum.
Of the above statements:

Match the electromagnetic radiations given in List-$I$ with their uses given in List-$II$.
| List-$I$ | List-$II$ |
| :--- | :--- |
| $A$) $X$-rays | $P$) Remote switches |
| $B$) $UV$-rays | $Q$) Finger prints in forensic labs |
| $C$) Radio waves | $R$) Crystal structure study |
| $D$) $IR$-rays | $S$) $TV$ communication system |

Match List-$I$ with List-$II$:

List-$I$ ($EM$ Wave)	List-$II$ (Wavelength Range)
$(A)$ Infrared	$(i)$ $ < 10^{-3} \, nm$
$(B)$ Ultraviolet	$(ii)$ $400 \, nm$ to $1 \, nm$
$(C)$ $X$-rays	$(iii)$ $1 \, mm$ to $700 \, nm$
$(D)$ Gamma rays	$(iv)$ $1 \, nm$ to $10^{-3} \, nm$

Choose the correct answer from the options given below:
