Which of the following electromagnetic radiations has the smallest wavelength?

Match the following types of waves with their wavelength ranges:

$i$. Microwave	$(a)$. $700 \ nm$ to $400 \ nm$
$ii$. Visible light	$(b)$. $1 \ nm$ to $10^{-3} \ nm$
$iii$. Ultraviolet	$(c)$. $0.1 \ m$ to $1 \ mm$
$iv$. $X$-rays	$(d)$. $400 \ nm$ to $1 \ nm$

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R.$
Assertion $A:$ $EM$ waves used for optical communication have longer wavelengths than that of microwaves employed in $RADAR$ technology.
Reason $R:$ Infrared $EM$ waves are more energetic than microwaves (used in $RADAR$).
In the light of the given statements,choose the correct answer from the options given below:

Which of the following radiations of electromagnetic waves has the highest wavelength?

Which of the following statements is wrong?

The energy of a gamma $(\gamma)$ ray photon is $E_{\gamma}$, and that of an $X$-ray photon is $E_{X}$. If the visible light photon has an energy of $E_{v}$, then we can say that:
