As data travels further over a wavelength or frequency, the radiation type goes down.
<h3>What is an electromagnetic spectrum?</h3>
An electromagnetic spectrum can be defined as a range of frequencies and wavelengths into which an electromagnetic wave is distributed into.
In Science, the electromagnetic spectrum consist of the following types of energy from highest to lowest frequency and shortest to longest wavelength:
In this context, we can infer and logically deduce that as data travels further over a wavelength or frequency within the electromagnetic spectrum, the radiation type goes down.
