Visible light
By radiation, mostly infra red, visible, and ultra violet EM radiation
Visible light waves
EM radiation higher in frequency than violet visible light but lower in frequency than soft x-rays.
Ultraviolet radiation and shorter waves are consider "shortwave radiation" they begin at about 300 to 350 nm (just past violet in the visible spectrum)
violet
The visible spectrum between red and violet.
Ultraviolet radiation is of higher energy than visible light. Ultra-violet suggests that it is above violet in the spectrum, and the colour violet is the uppermost region of visible light.
By definition, ultra-violet light is outside the visible spectrum of EM radiation. Thus it is defined as invisible.
Ultra violet radiation has more energy (E=hf) than visible radiation.
The part between 400 and 700 nanometers called the visible spectrum. Red to Violet.
No. It is electromagnetic radiation, beyond the violet end of the visible spectrum.
Visible light
Ultra violet Infrared Visible light.....i think
yes in fact cats and dogs do see things in ultraviolet lightm if you are wondering what ultra violet light is it is form of radiation whitch is not visible to the human eye
"UV" (ultra-violet) is radiation with shorter wavelength/higher frequency than visible. Infrared is radiation with longer wavelength/lower frequency than visible.
Astronomers study as much of the spectrum of radiation as they can, and the visible spectrum is only a small segment of it.
