Light.
The visible spectrum is one band within the full range of electromagnetic radiation.
It is light.
Blue light is in the visible wavelength range.
380nm to 750nm.
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.
The transfer of heat by electromagnetic radiation is called thermal radiation. It is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.
Blue light is in the visible wavelength range.
The electromagnetic radiation (excluding the visible range) that pervades the universe.
A very narrow range.
Visible light is a small region of the electromagnetic spectrum that is characterized by a specific range of wavelengths and frequencies
The eye detects electromagnetic radiation in the narrow range typically called visible light.
Infrared (or radiant heat).
