E=(hC/λ)=hV λ=(C/V)=(108/1019) =1011 m =10-2 nm Magnetron valve generate microwaves.

List I		List II
a	$700 nm$ to $1 mm$	i	Vibration of atoms and molecules.
b	$1 nm$ to $400 nm$	ii	Inner shell electrons in atoms moving from one energy level to a lower level.
c	$< 1 0^{- 3} nm$	iii	Radioactive decay of the nucleus.
d	$1 mm$ to $0.1 m$	iv	Magnetron valve.

(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)

(a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)

E=λhC​=hVλ=VC​=1019108​ =1011m=10−2nm Magnetron valve generate microwaves.

$E = \frac{h C}{λ} = hV λ = \frac{C}{V} = \frac{1 0 ^{8}}{1 0 ^{19}}$
$= 1 0^{11} m = 1 0^{- 2} nm$
Magnetron valve generate microwaves.
