It is in the<em><u> microwave radiation spectral band.</u></em>
<h3><u>Explanation</u>;</h3>
<em><u>Electromagnetic radiations are types of electromagnetic wave classified in terms of their frequency and wavelength and are part of electromagnetic spectrum.</u></em>
<em><u>Electromagnetic radiations are transmitted in waves or particles at different wavelengths and frequencies.</u></em>
<em><u>Microwaves are part of the electromagnetic spectrum with a wavelength ranging from about one centimeter to one millimeter, and frequencies between 300 MHz and 300 GHz. </u></em>
Protons have a positive charge. The number of protons in a nucleus determines the identity of the atom (element) and this number is called the atomic number.
