Microwaves are used in the following:

Fingerprints on a piece of paper may be detected by sprinkling fluorescent powder on the paper and then looking at it under:

Frequencies of various radiations are given as:
$v_v \rightarrow$ Visible light
$v_r \rightarrow$ Radio Wave
$v_{uv} \rightarrow$ Ultraviolet Waves
Then which of the following is true?

To which region of the electromagnetic spectrum does the frequency $1\, GHz$ correspond?

What is the frequency range of microwaves?

One requires $11 \ eV$ of energy to dissociate a carbon monoxide molecule into carbon and oxygen atoms. The minimum frequency of the appropriate electromagnetic radiation to achieve the dissociation lies in
