Visible light spectrum.
No, its just visible light - light is part of the electromagnetic spectrum and is in the middle of it.
when dispersed through a prism: Visible spectrum of light (rainbow) part of (very small fraction) electromagnets spectrum
This is part of the Electromagnetic radiation spectrum, visible light occupies a small part of this spectrum, but all wavelengths have the same physical properties
Visible light is a small part of the electromagnetic spectrum.
That part is called "visible light", or just "light".
Its not. You can't see ultraviolet. (it lies just above the visible spectrum.)
No, the visible part is called visible light. Ultraviolet is invisible to the human eye.
No, the visible part is called visible light. Ultraviolet is invisible to the human eye.
No reason. Light is an electromagnetic wave so you can call any part of the spectrum either.
Yes.
Visible light is a very small part of the EM spectrum and it is intellectual laziness to refer to all EM radiation as light.
No, light is not part of the radio spectrum. But, both the radio spectrum and light are part of the electromagnetic spectrum. The electromagnetic spectrum is a range of frequencies from very low to very high. Light frequencies are higher than radio frequencies but both are the same kind of thing.
