The wavelength of <u>light</u>.
<h2>
Explanation:</h2>
The electromagnetic spectrum shows the parts of light orchestrated by their wavelengths. The range for the most part comprises of both visible as well as invisible light. Together, they are called electromagnetic radiation. They are electromagnetic in light of the fact that they comprise of both an electric field and an magnetic field, and these fields travel in wave and travel at the speed of light: 3.00 × 
m/s.
When the light gets scattered it gives out color in the form of VIBGYOR which is elaborately called as Violet, Indigo, Blue, Green, Yellow, Orange and red. These colors are arranged in the spectrum based upon the wavelength.

Answer:
Bacteria that metabolize NO2- to give rise to NH4+ belongs to the family of denitrifying bacteria and nitrate ammonification bacteria such as pseudomonas.
Explanation:
Denitrifying bacteria uses NO2- as electron aceeptor thus converting the nitrite ion (NO2-) to ammonium ion(NH4+).
a) The above reaction is a reduction reaction because NO2- or nitrite ion accept electron to generated its reduced form known as ammonium(NH4+).
b) NO2- acting as electron acceptor in this reaction.
