You should look at it the other way round. The word 'ultra' means 'beyond', so you have the visible spectrum which ends at violet, then what is beyond is 'ultra violet'.
No. Normal human eyes are unable to see ultraviolet at all. People with aphakia say it looks pale blue. The author of this answer says it looks yellow but may be unique in this perception.
It doesn't look anything. The human eye can't see it at all. You can't even tell if ultraviolet light is there or not.
Actually, the part of the electromagnetic spectrum that we can see is called visible light, not ultraviolet light. Ultraviolet light is outside the visible spectrum and is not visible to the human eye.
No, ultraviolet light is not visible to the human eye. It has a shorter wavelength than visible light, which makes it invisible.
infrared light and ultraviolet light
No, the human cannot see ultraviolet rays with the naked eye.
No, the visible part is called visible light. Ultraviolet is invisible to the human eye.
Two types of light are visible light, which can be seen by the human eye, and ultraviolet light, which is invisible to the human eye but has shorter wavelengths than visible light.
100kHz and 101kHzA2. I think the questioner wants Ultra violet and Infra red.
The human eye cannot see ultraviolet and infrared light, as well as certain colors outside the visible spectrum.
Some examples of colors not visible to the human eye include ultraviolet and infrared light.
