Visible light is a very small part of the EM spectrum and it is intellectual laziness to refer to all EM radiation as light.

Assuming that you mean light in the visible spectrum, it would mean that the thing is giving of radiation that is in the visible light spectrum


Why astronomers study radiation beyond the violet end of visible light and beyond the red end of visible light?

Astronomers study as much of the spectrum of radiation as they can, and the visible spectrum is only a small segment of it.


What is the range of light called?

The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.


Is the light emitted by fireflies is considered visible radiation?

Yes, the light emitted by fireflies is considered visible radiation. It falls within the visible spectrum of light that can be seen by the human eye.


What kinds of visible radiation are included in the electromagnetic spectrum?

How is seeing related to wavelength?

The human eye can only detect electromagnetic radiation in the visible spectrum, Typically, wavelengths of 390 to 750 nm fall within the visible spectrum. Radiation with these wavelengths are called visible light or simply light.


What means to gives out light?

To give out light means to emit photons or electromagnetic radiation in the visible spectrum, making an object or source visible to the human eye. Light can be produced naturally (such as sunlight) or artificially (such as light bulbs or LEDs).


Is violet radiation visible to human?

No, violet radiation is not visible to the human eye. It falls outside of the visible spectrum of light for humans, which ranges from violet to red.


How is infrared radiation different from visible radiation?

Both are examples of electromagnetic radiation. Infrared has a longer wavelength (lower frequency) than visible light. Of course visible light is visible to humans and infrared is not (although long wave Infrared is sensible to humans as heat).


Is ultraviolet radiation visible or invisible?

By definition, ultra-violet light is outside the visible spectrum of EM radiation. Thus it is defined as invisible.
