If we could see the radiation used in 5G cell signals, it would not have a visible appearance similar to ordinary light or colors. The radiation used in 5G cell signals falls within the radiofrequency (RF) range of the electromagnetic spectrum, which is beyond the range of human visual perception.
The visible spectrum, which includes the colors we can see, spans from approximately 400 to 700 nanometers (nm). Radiofrequency waves, including those used in 5G signals, have much longer wavelengths ranging from several millimeters to tens of centimeters, well beyond the range of visible light.
Since we can't directly perceive radiofrequency radiation, if it were visible, it might appear as waves with much larger wavelengths than visible light. However, keep in mind that visualizing electromagnetic radiation is purely hypothetical, as our eyes are not naturally equipped to detect those wavelengths.
It's worth noting that while we can't see radiofrequency waves, they still play a vital role in wireless communication and technologies like 5G. These waves enable the transmission of data wirelessly over long distances, allowing for faster and more reliable mobile communications.
