Answer:
Frequency and wavelength are the properties used to organize waves in the electromagnetic spectrum.
Step-by-step explanation:
Electromagnetic spectrum, is a term used to describe the distribution of electromagnetic waves in a given space. The waves of this electromagnetic spectrum are organized according to the frequency and length of each where it can be visible or not.
It is possible to organize the electromagnetic waves according to these characteristics because the bodies that have the capacity to radiate energy, are able to radiate the waves with different lengths and frequencies.
