Which rays are not a portion of the electromagnetic spectrum?

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:

The correct match between the entries in column $I$ and column $II$ is:
$I$ (Radiation) | $II$ (Wavelength)
$(a)$ Microwave | $(i)$ $100 \, m$
$(b)$ Gamma rays | $(ii)$ $10^{-15} \, m$
$(c)$ $A.M.$ radio waves | $(iii)$ $10^{-10} \, m$
$(d)$ $X$-rays | $(iv)$ $10^{-3} \, m$

Write the range of wavelength of $X$-rays.

If microwaves,$X$ rays,infrared,gamma rays,ultraviolet,radio waves and visible parts of the electromagnetic spectrum are denoted by $M, X, I, G, U, R$ and $V$ respectively,then which of the following is the arrangement in ascending order of wavelength?

Match List-$I$ with List-$II$.

List-$I$	List-$II$
$A$. Microwaves	$I$. Physiotherapy
$B$. $UV$ rays	$II$. Treatment of cancer
$C$. Infra-red rays	$III$. Lasik eye surgery
$D$. $X$-rays	$IV$. Aircraft navigation
