Arrange the following electromagnetic radiations per quantum in the order of increasing energy :-
$A$ : Blue light
$B$ : Yellow light
$C$ : $X$-ray
$D$ : Radiowave

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

List-$I$ (Electromagnetic waves)	List-$II$ (Wavelength)
$(a)$ $AM$ radio waves	$(i)$ $10^{-10} \, m$
$(b)$ Microwaves	$(ii)$ $10^{2} \, m$
$(c)$ Infrared radiations	$(iii)$ $10^{-2} \, m$
$(d)$ $X$-rays	$(iv)$ $10^{-4} \, m$

Choose the correct answer from the options given below:

Light of wavelength $1 \,nm$ belongs to the following class of waves:

Cellular phones use radio waves to transmit voice communication in the . . . . . . band.

The terminology of different parts of the electromagnetic spectrum is given in the text. Use the formula $E = hv$ (for energy of a quantum of radiation: photon) and obtain the photon energy in units of $eV$ for different parts of the electromagnetic spectrum. In what way are the different scales of photon energies that you obtain related to the sources of electromagnetic radiation?
