What range of electromagnetic spectrum is considered as light?

Match the following Maxwell's equations:
(The symbols used here have their usual meanings)

List-I		List-II
(a)	Gauss' law for electrostatics	(i)	$\oint \vec{E} \cdot d\vec{A} = \dfrac{Q}{\varepsilon_0}$
(b)	Gauss' law for magnetism	(ii)	$\oint \vec{B} \cdot d\vec{l} = \mu_0 \left[i_c + \varepsilon_0 \dfrac{d\phi_E}{dt}\right]$
(c)	Faraday's law	(iii)	$\oint \vec{B} \cdot d\vec{A} = 0$
(d)	Ampere-Maxwell's law	(iv)	$\oint \vec{E} \cdot d\vec{l} = -\dfrac{d\phi_B}{dt}$
