Answer:

recording the wavelength of light

Explanation:

When an appropriate measure of energy say in the form of light of a certain wavelength, is supplied, electrons have a tendency to absorb the energy and get excited to a higher energy level. Conversely, if an electron is already at a higher energy state it will emit energy in the form of light (or heat) and return to a more stable lower energy state.

Oxidation number of fe in the compound...,

Let the oxidation number of (Fe) be x

The oxidation number of oxygen(o) is (-2)

; 3x + 4(-2) = 0...where zero is the total charge on the compound(fe3o4)

; 3x = 8...then divide both sides by 3

Oxidation number of fe is( 2.67 )
