In a microwave oven,which type of waves are used?

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 the List-$I$ with List-$II$:

List-$I$	List-$II$
$A$. Microwaves	$I$. Radioactive decay of the nucleus
$B$. Gamma rays	$II$. Rapid acceleration and deceleration of electrons in aerials
$C$. Radio waves	$III$. Inner shell electrons
$D$. $X$-rays	$IV$. Klystron valve

Choose the correct answer from the options given below:

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:
