The part of the electromagentic spectrum from the bottom of the AM radio dial ... 550 KHz ...
to the lowest-frequency gamma rays ... 1019 Hz ... covers roughly 44 octaves.
Out of that, roughly one octave is visible to the human eye. (maybe 380 - 750 nanometers)
visible light
The visible portion of electromagnetic spectrum is called the visible light and is the electromagnetic wave with the wavelength between 380 - 740 nm.
in electromagnetic spectrum visible light is safe for humans
Between 400nm and 700nm
No, its just visible light - light is part of the electromagnetic spectrum and is in the middle of it.
Visible light is a small section in the electromagnetic spectrum.

Yes. visible light is in the electromagnetic spectrum.
The visible spectrum is a tiny, almost negligible slice of the electromagnetic spectrum. 'Sonar' has no place in this discussion. It's not even electromagnetic.

The visible spectrum is one band within the full range of electromagnetic radiation.
Most of the electromagnetic spectrum is not visible.

I suppose you mean the visible spectrum, only a small part of the entire electromagnetic spectrum. The visible spectrum is basically all of the colors the human eye can detect.
