A2. I think the questioner wants Ultra violet and Infra red.

The part of the electromagnetic spectrum you can see is called ultraviolet light?
No, the visible part is called visible light. Ultraviolet is invisible to the human eye.
Why do some materials glow in ultraviolet - UV - light?
UV light is invisible to the human eye, which is why it is sometimes referred to as 'black light'. However, some materials (e.g. DayGlo) can absorb UV energy and convert it into visible light energy. They are said to be fluorescent.
What is difference between visible and infrared light?
Visible light is visible (for the human eye), infrared is not. Infrared has a longer wavelength, and a higher frequency. visible light is visible to human i.e the VIBGYOR, above vibgyor are ultravoilet light which is not visible to human eye and below vibgyor are infrared light which is also not visible to human eye.
Which wave can your eye detect?
If you mean, "which wavelengths of light can the human eye detect," the human eye can see wavelengths from about 390 to 700 nanometers.
Which type of energy is visible with the human eye?
Light.
What wavelenghts are invisible to the human eye?
All wavelengths outside the range of 380 - 750nm are invisible to the human eye.
The part of the electromagnetic spectrum you can see is called ultraviolet light?
No, the visible part is called visible light. Ultraviolet is invisible to the human eye.
Is the part of the electromagnetic spectrum you can see called ultraviolet light?
No, the visible part is called visible light. Ultraviolet is invisible to the human eye.
What is invisible but can be seen by the naked eye?
Light
Why is there such thing as invisible?
The definition of 'invisible' is "Anything in which the naked human eye cannot see is invisible." Well, that's the definition in most dictionaries. But anything that cannot be seen by your naked eye is either too small or does not have enough or any light reflecting off of it well enough to allow you to see it.
What color is invisable too the eye?
The human eye can only perceive the colors from violent to red. All colors that have a wave frequency higher than violent, "ultra-violent", and have a wave frequency lower than red, "infra-red", are invisible to the human eye. Since we cannot see these colors, we do not have names for them other than their frequencies.
Is human eye sensitive to red light?
yes the human eye is sensitive to red light
When a room is dark are the colors of everything still there?
Colour is the human perception of certain frequencies of light. Without light, there is no colour to be perceived. A dark room may still have light in it (and in fact it does in the form of infrared light), but the intensity of that light is small, and the human eye may not be able to see it.In short, no light = no colour.
What is red and invisible?
Red is a color that is visible to the human eye, so it cannot be both red and invisible at the same time.
How are telescopes used?
Telescopes are made to view distant objects that cannot be seen clearly with the human eye. Many telescopes only collect light that is visible to the human eye, but others can collect different frequencies of electromagnetic radiation including x-rays, ultraviolet, and infrared.
Is there such thing as invisibility?
The definition of 'invisible' is "Anything in which the naked human eye cannot see is invisible." Well, that's the definition in most dictionaries. But anything that cannot be seen by your naked eye is either too small or does not have enough or any light reflecting off of it well enough to allow you to see it.
What type of wave is a UV light?
A UV light radiates energy in the form of electromagnetic waves with wavelengths shorter than those of violet light but longer than those of x-rays. The radiation is invisible to the human eye.
