Marks: +1, -0

Choose the correct option related to wavelengths
(

λ

) of different parts of electromagnetic spectrum.

$λ_{\;\text "x-rays "\;}< λ_{\;\text "micro waves "\;}< λ_{\;\text "radio waves "\;}< λ_{\;\text "visible "\;}$
$λ_{\;\text "visible "\;}>λ_{x \;\text "-rays "\;}>λ_{\;\text "Tadio waves "\;}>λ_{\;\text "micro waves "\;}$
$λ_{\;\text "radio waves "\;}>λ_{\;\text "micro waves "\;}>λ_{\;\text "visible "\;}>λ_{x \;\text "-rays "\;}$
$λ_{\;\text "visible "\;}< λ_{\;\text "micro waves "\;}< λ_{\;\text "radio waves "\;}< λ_{\;\text "x-rays "\;}$
